New materials for energy and information storage and transmission

The Department of Physics at SRM University-AP is organising the second edition of the Eminent Guest Lecture Series: An Odyssey of Physics on July 24, 2021, Saturday at 3.00 pm. The session will be engaged by Prof S Patnaik from the School of Physical Sciences in Jawaharlal Nehru University, New Delhi on the subject “New Materials for Energy and Information Storage and Transmission”. Prof. V S Rao, Vice-Chancellor; Prof. D. Narayana Rao, Pro-Vice-Chancellor; Prof. C Durga Rao, Associate Dean, SLASS; Prof. Ranjit Thapa; Prof. Amit Chakraborty; and Prof. Pranab Mandal from the Department of Physics at SRM University-AP will be the panellists for the session.

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. (Y2CoMnO6) and h) new ideas on solar energy and battery applications.
