Quantum ferroelectric materials, such as bulk SrTiO3, exhibit complex Rashba-type electron-phonon interactions due to broken inversion symmetry. These interactions can significantly alter low-temperature properties near the quantum critical point (QCP), affecting transitions from paraelectric to ferroelectric phases, as well as superconductivity and unique quantum transport phenomena. My primary research focuses on understanding how these interactions influence electron and spin properties near the QCP. Specifically, I investigate how they modify quantum kinetic equations and transport coefficients in bulk systems. Another key area of my research explores how out-of-equilibrium properties are shaped by the topology of the bulk electronic band structure in Weyl semimetals.

My research interest lies in complex systems. We investigate the roles of fluctuations and time delay in non-equilibrium reaction systems. We analyse the data generated by complex systems such as time series data of earthquakes or two dimensional spatial images for multifractality. Fractal dimension is an important measure of complexity. Recently, I am interested in complex biological systems. Complex diffusion dynamics is ubiquitous in complex biological systems such as living cells. In particular, I am interested in the transport dynamics of active particles in complex environment. We investigate anomalous diffusion dynamics of these active particles with stochastic modelling, statistical analysis and data science approaches.

My research primarily focuses on aspects of Matrix Models and their applications in understanding gauge theories and holography. In particular, concrete computations gives us a better understanding of holography in lower-dimensional setting where certain observables become exactly tractable. However, there is still a lot to learn even in lower dimensional gauge theory and gravity in their respective non-perturbative regime. Using the technology of resurgence, I intend to develop a systematic procedure to understand the non-perturbative effects of low dimensional gauge theories (such as 2D Yang-Mills), matrix models and also simple 2D gravitational theories (such as JT gravity). This will further shed light and provide is with valuable insights into the rich phase structure and free energy of various phases of these apparently simple looking theories. We will also attempt to identify the universal features which will further carry over to generic higher-dimensional theories.

Non-equilibrium thermodynamics of open quantum system is a powerful tool to study mesoscopic systems and quantum engines. I am interested in studying the thermodynamical aspect such as work statistics of a quantum system far from equilibrium and the relation to quantum informational quantities such as entanglement propagation. Recently, I have been investigating the quantum work of integrable and chaotic many-body systems. I plan to pursue these direction further to open systems as well as the application in quantum technology such as in quantum batteries. I approach the problem by employing both analytical and numerical treatments. Many of the proposed models can be realized in state-of-the-art experiments.

My main research interest is examining the relation between string theory and QCD, utilizing the two possible approaches of holographic QCD on one hand, and effective string theory on the other. In particular, I am currently working on computing scattering amplitudes of hadrons using these tools. Recently I have worked on the study of chaotic behaviour in string theory, and on constructing interacting supersymmetric higher spin gravity theories.

The study of quantum gravity is put to the test in the context of black holes. The fact that black holes are thermodynamic objects with temperature, entropy, and the ability to emit thermal radiation—a discovery made by J. Bekenstein and S. Hawking—gives us a clear direction for understanding black holes and their microscopic quantum structure. My research focuses on investigating the thermodynamics of black holes as they emerge from string theory. By using deformed supergravities and the higher derivative supersymmetric actions provided by the superconformal calculus, I would like to analyze the issues from both macroscopic and microscopic perspectives. Using the quantum entropy formalism given by Ashoke Sen one accurately and methodically captures the quantum effects on black hole entropy, some of the approaches enable us to give string theory with precise tests as a contender for a theory of quantum gravity. In the future, I will continue to research distinct thermodynamic characteristics of extended objects or black holes in various ensembles.

The electronic structure of condensed matter governs its properties and is influenced by factors such as atomic composition, structural arrangement, bonding interactions, and quantum effects. These factors are essential for understanding material behavior and functionality. My research focuses on using density functional theory (DFT) and computational many-body techniques beyond DFT to investigate condensed matter systems. Recently, I have been working on 2D Janus materials, which display broken symmetry at the atomic level and give rise to nontrivial behaviors. By conducting electronic structure calculations, I seek to understand how the unique features of Janus materials relate to their symmetry and structural properties.

The Higgs boson discovery serves as the evidence for the importance of scalar in elecroweak symmetry breaking. However, the order of phase transition and the role of additional scalar or multiplets is yet to be discovered. My research focusses on fate of the electroweak vacuum and the order of phase transition. I am interested in studying the order of phase transition with the dark matter constraints from new packages as MadDM and GAMBIT. I am also interested in exploring the effect of CP-violating pahses in explaining the baryon asymmetry of the Universe in beyond Standard Model scenarios.

In the laboratory, space, and astrophysical plasma environment, the proper understanding of dusty plasma and wave propagation characteristics are crucial in diverse fields such as laboratory applications (fusion devices, semiconductor industry, etc.) and spacen exploration. The charge perturbation induced on the equilibrium space dusty plasma by the space debris and meteoroids affects the linear and nonlinear wave properties. Recently, I am focused on dust dynamics, dust charge fluctuations, dust levitation, sheath characteristics of the lunar surface (sheath instability due to the presence of charge dust particles as Rayleigh-Taylor instability), Landau damping phenomenon, linear and nonlinear wave properties in the magnetized and unmagnetized laboratory, space and astrophysical dusty plasmas. In addition, I am interested in exploring the plasma wave dynamics on strongly and weakly coupled magnetized astrophysical dusty plasma, wave instabilities driven by temperature anisotropy, quantum dusty plasma applications to neutron stars, and particle transport phenomenon in rotating plasma (astrophysical and space plasmas).

My research centers around twistor theory. It can be thought of as a practical framework to construct viable gravitational models that are UV-finite, such as self-dual gravity and chiral higher-spin theories. I am currently using twistor theory to study the integrability of some self-dual/chiral gravitational models both at classical and quantum level. Using some current known techniques in twistor theory, I also aim to construct some simple models that can describe interactions of massive higher-spin fields, from which the black hole scattering processes in the post-Minkowskian approximation can be studied.
