Dr Soumyajyoti Biswas, Assistant Professor in the Department of Physics, along with his Doctoral Scholar, Mr Soumyaditya Das, have presented groundbreaking findings through their research work titled “Critical Scaling through Gini Index”. The research paper was featured in the prestigious Physical Review Letters, which has an impact factor of 9.161.
In the systems showing critical behaviour, various response functions have a singularity at the critical point. Therefore, as the driving field is tuned toward its critical value, the response functions change drastically, typically diverging with universal critical exponents. In this Letter, we quantify the inequality of response functions with measures traditionally used in economics, namely by constructing a Lorenz curve and calculating the corresponding Gini index. The scaling of such a response function, when written in terms of the Gini index, shows singularity at a point that is at least as universal as the corresponding critical exponent. The critical scaling, therefore, becomes a single parameter fit, which is a considerable simplification from the usual form where the critical point and critical exponents are independent. We also show that another measure of inequality, the Kolkata index, crosses the Gini index at a point just prior to the critical point. Therefore, monitoring these two inequality indices for a system where the critical point is not known can produce a precursory signal for imminent criticality. This could be useful in many systems, including condensed matter, bio- and geophysics to atmospheric physics. The generality and numerical validity of the calculations are shown with the Monte Carlo simulations of the two-dimensional Ising model, site percolation on the square lattice, and the fibre bundle model of fracture.

Collaborations and Future Plans
This work essentially builds a framework for indicating imminent critical points for any system. Therefore, in situations where such knowledge is vital, for example, in the fracture of solids, the method is going to be highly useful in forecasting the failure point. We are in the process of working with our collaborators at the University of Barcelona to experimentally verifying our methods for the compressive failure of porous samples. This is a significant first step towards opening new pathways in forecasting fracture points in disordered materials that could have an impact on laboratory-scale fractures to large constructions and eventually to earthquakes.
We wish the teacher-student duo many more fulfilling and enriching research endeavours in future!

The Department of Mechanical Engineering is delighted to share that Dr Supen Kumar Sah, Assistant Professor, Department of Mechanical Engineering, has received the best paper award for his paper titled “Free Vibration Analysis of Functionally Graded Material Sandwich Plate Using Refined Shear Deformation Theory” in the 2nd International Conference on Modern Research in Aerospace Engineering (MRAE 2023). Dr Supen collaborated with Saloni Malviya of VIT, Bhopal, for the research paper. The paper explores the intricate dynamics of functionally graded material sandwich plates, employing a refined deformation theory. Dr Sah’s exceptional work has not only contributed to the scientific community but has also demonstrated his dedication and passion for advancing knowledge in the field of materials science and engineering.
In the present study, free vibration analysis of a functionally graded material sandwich plate has been carried out using refined shear deformation theory. The shear correction factor is not needed since the parabolic variation of shear strain through the thickness is in such a way that shear stresses vanish on the plate surfaces. Hamilton’s principle is used for the derivation of the equation of motion for the theory. Additionally, Navier’s solution is used to obtain the eigenvalue equation for the sandwich plate. The three variants of sandwich plate are chosen for the analysis. To carry out the free vibration analysis three different types of FGM sandwich plate models namely 1-1-1, 1-2-1, and 2-2-1 have been considered. A power law defines the volume fraction index and the material properties of the individual layers of the sandwich plate. Lastly, the impact of parameters such as volume fraction, aspect ratio, and length-to-width ratio on frequency parameters is investigated.
Future Research Plans
• Modelling and Analysis of porous uni and multi-directional Functionally Graded Material (FGM) plates to obtain the impact of porosity distributions over structural responses.
• Analytical and finite Element Solutions for static and dynamic response of FGM sandwich plates employing non-polynomial shear deformation theories under elastic foundation.
