The Department of Physics is organising a Faculty Development Program on ‘Scope for Sponsored Projects and its Implementation’ with eminent academicians, Prof Sathish Vadhiyar, Chair, Supercomputer Education and Research Centre, IISc Bangalore and Prof Kothandaraman Ramanujam, Indian Institute of Technology, Madras.

Date: May 11, 2022

Time: 10.00 am

Venue: ALC 3rd Floor

Discussing the scopes and challenges of such sponsored projects is inevitable as it determines the progress in its execution. Documenting a list of the project goals, deliverables, tasks, costs and deadlines is, therefore, an important part of this process. This will help in establishing the objectives of the project, analysing its limits, and providing a roadmap to move ahead.

Prof Sathish Vadhiyar will deliver a talk on the National Supercomputing Mission (NSM) Program which was introduced by the government of India with an aim to connect national academic and R&D institutions with a grid of high-performance computing facilities. This is an effort to improve the number of supercomputers owned by India. Prof Kothandaraman Ramanujam will provide a brief awareness regarding consultancy projects set up with the industry through his talk. The session will be wrapped up by Prof Paromita Chakraborty who will give an overview of funded projects and bilateral projects.

non equilibrium dynamics interacting particles

The Department of Physics is going to host the sixth instalment of the Eminent Guest Lecture Series: An Odyssey of Physics on March 19, 2022, at 03.00 PM IST with Prof Parongama Sen from the University of Calcutta as the keynote speaker. Dr Sen will be speaking on” Non-equilibrium dynamics of interacting particle systems with annihilation”.

Prof Parongama Sen has been teaching at the University of Calcutta as Professor since 2008. She received her PhD from Saha Institute of Nuclear Physics, Calcutta in 1993. She was also awarded APS-IUSSTF Professorship in 2012-13. Her research interests include statistical physics: phase transitions and critical phenomena in magnetic systems, networks, quantum systems, percolation etc. and dynamical phenomena in complex physical and social systems.

Non-equilibrium dynamics of interacting particle systems with annihilation

There has been tremendous research activity on the evolution of systems comprising of interacting particles in Statistical Physics over the last few decades. This lecture particularly considers those systems in which the particles (also called reactants) may get annihilated instantaneously upon contact or merged as a single species, both of which reduce the particle number. Some of these processes have a one-to-one correspondence with the coarsening dynamics of spin systems and play an important role in the development of non-equilibrium Statistical Physics.

Usually, one considers diffusive motion when the particles move freely, and some known results in this context will be discussed. Here, the speaker notes that the dynamics may also be considered in terms of population densities rather than individuals and examples include models of epidemic spreading.

Finally, she will focus on a model in which the reactant particles are driven by a dynamic bias that radically changes the scaling behaviour of the relevant quantities. The results will be presented for such a system, highlighting the microscopic dynamics, which reveal a crossover behaviour.

Programme Schedule of the Invited Lectures:

Time: 10.05 – 11.05 AM (IST)
Speaker: Prof Vineeth N Balasubramanian (IIT Hyderabad)
Title: Explainable Deep Learning: Overview, Trends and Challenges

Abstract: The last decade has seen rapid strides in Artificial Intelligence (AI) moving from being a fantasy to a reality that is a part of each one of our lives, embedded in various technologies. A catalyst of this rapid uptake has been the enormous success of deep learning methods for addressing problems in various domains including computer vision, natural language processing, and speech understanding. However, as AI makes its way into risk-sensitive and safety-critical applications such as healthcare, aerospace and finance, it is essential for AI models to not only make predictions but also be able to explain their predictions. This talk will introduce the audience to this increasingly important area of explainable AI, describe salient methods in explainable deep learning, discuss open challenges as well as present some of our recent research in this domain.

Time: 11.30 AM – 12.30 PM (IST)
Speaker: Dr Girish Varma (IIIT Hyderabad)
Title: Deep Generative Methods and Applications

Abstract: Generative methods deals with the modelling of complex high dimensional probability distributions. With the advent of deep neural networks, these methods have become more common with the discovery of new techniques like GANs. Such methods can learn to generate images, graphs etc even without using labelled data. In this talk, we will give some of the common deep generative modelling techniques like GANs, Variational Autoencoders, Normalizing Flows. We will also look at some example applications in Style Transfer, Super Resolution in Computer Vision, Conditional Generation of Molecules in Physics etc.

Time: 2.00 – 3.00 PM (IST)
Speaker: Dr Sanmay Ganguly (University of Tokyo, Japan)
Title: The Deep Relation Between Particle Physics and Machine Learning

Abstract: At the CERN Large Hadron Collider (LHC) experiment, trillions of protons get smashed with each other at very high energies every second. Remnants of this collision are collected and studied to infer what fundamental interactions are happening at the core. Analysing and extracting meaningful physics information out of this large data is a highly challenging statistical analysis, part of which has to be carried out in real-time. Modern deep learning techniques have brought a change in paradigm in the whole field, where it is observed that the application of ML truly impacts at all corners. In this presentation the speaker will try to give a general overview of the ongoing ML activities, mainly highlighting the areas in the context of LHC physics and shortly touch other branches of HEP.

Time: 3.30 – 4.30 PM (IST)
Speaker: Prof Lasse Laurson (Tampere University, Finland)
Title: Machine Learning Plastic Deformation of Crystals

Abstract: The speaker will present an overview of our recent efforts to apply machine learning to predict the fluctuating plastic deformation process of small crystals, mediated by the stress-driven motion of dislocations. To this end, we use machine learning to establish mappings between the initial state of a sample and the corresponding stress-strain curve, considering different loading protocols and geometries of the dislocation assembly. He will start with a discussion of machine learning the depinning process of edge dislocation pileups, after which he will consider the problem of machine learning-based prediction of the stress-strain response of two- dimensional systems of discrete dislocations subject to stress-controlled and strain-controlled loading.

The discovery of Dirac and Weyl semimetals (WSM) has brought forth the condensed-matter realization of Dirac/Weyl fermions, which were previously theorised as low energy excitations in high energy particle physics. In the recent past, we have witnessed some exceptional developments in chalcogenide and pnictide materials that have been identified with such properties. Several age-old industrial materials based on selenides, tellurides, borides and oxides have come to the fore that promise to usher in a new understanding of correlated electronic systems. Towards material implementation of quantum computation, we shall review the electromagnetic properties of topological superconductor SrxBi2Se3 and study its pairing mechanism. Several transition metal mono-pnictides are under intense investigation for understanding the properties of inversion-symmetry broken Weyl semimetals. Non-trivial Berry phase and chirality are important markers for characterizing topological aspects of Weyl semimetals. We shall discuss aspects of exceptional magneto-resistance seen in the normal state of these topological semimetals. In specific, we shall summarize potential applications with regard to material properties of the following systems a) Single-stage cryocooled superconducting magnets for MRI (MgB2), b) Cables for lossless energy transmission and storage (Bi2Sr2Ca2Cu3O10), c) Materials to implement Quantum Computation (Sr intercalated Bi2Se3), d) Better read-heads for magnetic storage devices (NbP, TaSb2), e) Magnetic Nano-particles for Cancer therapy (Co+CoO EB), f) Thermoelectric materials for waste heat scavenging (ZrNiPb), g) Next-generation piezo devices using multiferroic materials.

The Department of Physics, SRM University-AP, Andhra Pradesh, organizes a continual online and offline Lecture Series entitled “Eminent Guest Lecture Series: An Odyssey of Physics” to understand the recent advances and future developments in the field of Physics and allied sciences. The first seminar of this lecture series, on the theme Beyond the Periodic Table of Elements is scheduled to be held on June 19, 2021 at 5.00 pm (IST). Prof Puru Jena, distinguished Professor of Physics at Virginia Commonwealth University, USA will enlighten and engage the session with his extensive knowledge and expertise in the domain.

Abstract: The periodic table created by Mendeleev in 1869 is the mother of all materials. The realization that the physics and chemistry of materials at the nanoscale can be very different from their bulk and that their properties in small clusters can be tailored one atom at a time led to the hypothesis, more than twenty years ago, that stable atomic clusters with specific size and composition and mimicking the chemistry of atoms can be designed and synthesized. These clusters, known as superatoms, can form the building blocks of a new three-dimensional periodic table as well as a new class of cluster-assembled materials. In this talk, Dr Puru Jena will outline the considerable progress that has been made over the years by focusing on superalkalis and superhalogens, which mimic the chemistry of alkalis and halogens, respectively and can be used to form supersalts with uncommon properties. The ionization energies of superalkalis are less than those of alkali atoms while the electron affinities of superhaloegns are larger than those of halogen atoms. He will present examples where these superions are used to promote unusual chemistry making noble gas atoms form chemical bonds at room temperature, superhalogens forming halogen-free electrolytes in Li-ion batteries, superalkalis as building blocks of new electrides where the electron is completely detached from the host and remain localized pretending to be an anion without a nucleus, superhalogens as building blocks of multiferroic materials, and supersalts capable of enhancing the Curie temperature of 2D materials. The synergy between first principles theory and experiments in advancing our understanding of matter at the nanoscale will be highlighted.

About the Speaker: Dr Puru Jena is a Distinguished Professor of Physics at Virginia Commonwealth University and received his Ph. D. in Physics from the University of California at Riverside. He also served as Program Director at the National Science Foundation and as Jefferson Science Fellow and Senior Science Advisor at the US Department of State. Dr Jena’s research covers a wide range of topics in Nano-structured Materials, Condensed Matter Physics, and Materials Science.

The Department of Physics, SRM University-AP, Andhra Pradesh, has organised a National Symposium on High Energy Physics on Saturday, May 1, 2021, at 11 am. Leading Physicists of the nation are going to share their perspective on the progress and recent challenges in Particle Physics, Dark Matter Physics and Gravitational-Wave Astronomy. Padma Shri awardee Prof Rohini Godbole, theoretical particle physicist at the Indian Institute of Science (IISc), Bengaluru, will present the inaugurating talk on “Status of Particle Physics: in light of Nobel Prizes of 2013 and 2015”. Prof Basudeb Dasgupta from the Tata Institute of Fundamental Research (TIFR), Mumbai, will join us for the next session on “The Mystery of Invisible Mass”. The last talk of the day will be given by Prof. Bala Iyer from the International Centre for Theoretical Sciences (ICTS), Bengaluru. He will shed light on “The Detection of Gravitational Waves and the Dawn of Multi-messenger Astronomy”.

Our first speaker of the day, Prof Rohini M Godbole, is a theoretical particle physicist at the Indian Institute of Science, Bangaluru. Over the past three decades, she has worked extensively on particle physics phenomenology, exploring different theoretical aspects of Standard Model and Beyond Standard Model physics at high energy collider experiments. She is an elected fellow of all the three Academies of Science of India and the Science Academy of the Developing World (TWAS). She has published over 200 research papers and received numerous recognitions from all over the world. Prof Godbole co-edited the book “Lilavati’s Daughters”, a collection of biographical essays on women scientists of India, which was published by the Indian Academy of Sciences. In 2019, she was awarded Padma Shri, the fourth highest civilian honour of the Government of India, for her contribution to Science and Technology.

In 2013, the Nobel prize in Physics was awarded for the theoretical postulate of the Higgs Boson, after the experimental discovery of the same at the LHC in 2012. This was considered being the last missing piece in the periodic table of the Standard Model (SM). In 2015 the Nobel prize in physics was awarded for the experimental discovery of Neutrino oscillations, which is one robust evidence for physics beyond the SM. In her speech, Prof Godbole will comment on the status of particle physics in light of these two and the exciting results on the measurements of the magnetic moment of the muon that have been announced in the previous weeks.

Prof Basudeb Dasgupta is a theoretical physicist at the Tata Institute of Fundamental Research (TIFR), Mumbai. His research interests include the interfaces of particle physics, astrophysics, and cosmology with an emphasis on dark matter and neutrino physics. Prof Dasgupta is also the Leader of the Astroparticle Physics Partner Group of Max-Planck Institute for Physics. Prof Dasgupta is a regular speaker at notable international workshops and conferences and different Science Outreach programmes.

When we look at the night sky, we see a variety of astronomical objects, such as planets, stars, gas clouds, still waiting to form stars to swathe of the emptiness. For a long time, it was believed to be all that the Universe is consists of. The following discoveries came as a huge surprise that all we see and know comprises only about 20% of the matters in the Universe. The remaining 80% is invisible and called “Dark Matter.” What is this dark matter? How do we know that is out there? What is it made of? How can we decipher the nature of this mysterious new ingredient of the cosmic soup? In this talk, Prof Basudeb Dasgupta will address and answer some of these questions.

Prof Bala Iyer is currently the Simons Visiting Professor at ICTS-TIFR Bangalore and CO-PI of the LIGO-India Scientific Collaboration. The alumnus of Bombay University previously worked at the Raman Research Institute, Bangalore, on Astrophysical applications of General Relativity, Perturbation methods and Black Holes. Since 1990, he is working on calculations of Gravitational waves from inspiraling binaries of neutron stars and black holes. He is a Fellow of the American Physical Society and International Society on General Relativity and Gravitation. He has been the Chair of the IndIGO Consortium since its inception in 2009. Prof Iyer was a Member of the Core Team for the LIGO-India Mega-Project Proposal. Further, he is the Chief Editor and Subject Editor of Gravitational Waves for the Online Journal `Living Reviews in Relativity’, published recently by Springer. Prof Bala Iyer has been a Visiting scientist in France, UK, Germany, USA. He has been involved in REAP (Research Education Advancement Programme) for B.Sc students at the Bangalore Planetarium for over two decades and Public outreach on General Relativity and Gravitational Waves.

The first detection of gravitational waves from a black hole binary in 2015 was a breakthrough, taking a century to realise, and made possible by the coming together of a remarkable experiment and an exquisite theory complemented by the best in sophisticated data analyses, state of the art computing and the transition to “big science”. 2017 brought the discovery of gravitational waves from a neutron star binary. The intense associated electromagnetic follow up of this event was spectacular. It heralds the launch of a new multi-messenger astronomy with the potential to impact astrophysics, cosmology and fundamental physics in the coming decades. Prof Bala Iyer will discuss the nature of gravitational wave and its impact on Physics.

The symposium aims to make students aware of the current status of some of the fascinating research topics of High Energy Physics. Students of basic sciences and engineering streams will be highly inspired and motivated after attending the symposium and listening to the talks. Join the captivating event on May 1, 2021, at 11 am.
