Superconductivity in strongly correlated systems: Heavy fermions, Cuprates, Infinite-layer Nickelates
The phase diagrams of the heavy fermion, transition-metal (copper-, nickel-) oxides materials have a wide variety of different phases. It is believed that, the strong correlation among electrons governs most of the ...
Electronic structure of two-dimensional materials: Effect of point defects and moiré patterns
In the last two decades, research on two-dimensional (2D) materials has gained momentum due to their capability to host a wide range of novel phases of matter. These materials have also found applications in electronic, ...
Transport, localization and entanglement in disordered and interacting systems: From real space to Fock space
In this thesis, we explore some of the exciting physics of condensed matter systems
manifested because of imperfection or disorder and interactions among the constituent
particles. In phenomena like transport, e.g., ...
Electrical waves in mathematical models of human-ventricular tissue: effects of different modeling formalisms, electrophysiological factors, and heterogeneities on ventricular arrhythmias and the termination of these arrhythmias via a deep-learning approach
Sudden cardiac death (SCD) remains one of the significant causes of
mortality in industrialized and developing countries. SCD is often caused by
life-threatening cardiac arrhythmias like ventricular tachycardia and ...
Role of Friction in Microswimmer and Active Filament Motion
Friction is pervasive in all fields of science. It is the key factor that emerging technologies involving autonomous motion at micron scales such as micro-bots need to overcome in order to be efficient. They fall in the ...
An Investigation of Electronic Phases and Charge Dynamics in Low-Dimensional System
In condensed matter physics, the concepts of topology and symmetry are of paramount importance, particularly in understanding quantum phase transitions. Topology classifies objects based on their topological
properties, ...
Structural signatures of relaxation mechanisms in glass forming and devitrifying colloidal suspensions
Connecting macroscopic behavior of matter to the microscopic interactions is the central goal of condensed matter physics. Yet, achieving such a challenging goal in atomic and molecular systems would require tracking all ...
Spectroscopic study of emitter assemblies coupled to Plasmonic nano-cavities and metamaterials
The plasma oscillations of noble metals as silver and gold are well understood from the free electron model of metals. In the past two decades, due to the availability of various physical and chemical fabrication methods ...
Quantum oscillation in band insulators and properties of non-equilibrium steady states in disordered insulators
Starting with the experiment on Kondo insulator SmB6 , which shows 1/B-periodic oscillations despite the absence of gapless electronic excitations in bulk, the candidate insulators showing quantum oscillation (QO) are on ...
Activity induced phase separation and the emergence of liquid crystal phases in chiral and achiral systems, and development of an efficient method to compute the entropy of various liquid crystal phases
The phase behaviour of shape-anisotropic particles is an emerging field of research that
gives rise to various liquid crystal phases. In this thesis, we explore various equilibrium and
non-equilibrium properties of ...
