Active matter: chirality, translational order, and interfaces
My PhD work is on chiral active matter with solid and fluid directions, dynamics of the interface of a nonconserved chiral order parameter in an active system, flocking on curved manifolds and field-driven colloids in ... -
Investigation of Optical and Electro-optical Effects at Material Interfaces
The key questions addressed in this thesis are related to light-matter interactions at the material interfaces and are related to both plasmonic as well as Pockels effects. Plasmonics enables the design of compact photonic ... -
Exploring dissipation dynamics in low-dimensional superconductor
Technological advances in the past decade in fabricating two-dimensional superconducting materials with low disorder have enabled exploring many exciting phases. In recent times, two-dimensional superconductors have been ... -
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 ... -
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, ... -
Investigations on deep-level defects in HgTe nanocrystals-based photovoltaic devices using a novel instrumentation for Deep Level Transient Spectroscopy
Colloidally produced nanocrystals (NCs) arranged in thin films hold promise for next-generation semiconductors. These NCs offer tunability in semiconductor properties due to their size, shape, composition, and surface ... -
Entanglement properties of gauge theories and the graviton.
Entanglement entropy is emerging as a useful quantity to study critical phenomena in quantum systems, black holes physics, and holography. In this presentation, we discuss entanglement properties of gauge theories and ... -
On some canonical metrics on holomorphic vector bundles over Kahler manifolds
This thesis consists of two parts. In the first part, we introduce coupled Kähler- Einstein and Hermitian-Yang-Mills equations. It is shown that these equations have an interpretation in terms of a moment map. We identify ... -
Exponential Resummation of QCD at Finite Chemical Potential
A comprehensive study of the QCD phase diagram is one of the challenging and open problems in high energy physics. Having significant astrophysical implications, this is also important in constructing the chronological ... -
Interaction of distinguished varieties and the Nevanlinna-Pick interpolation problem in some domains
This thesis explores the interplay between complex geometry and operator theory, focusing on characterizing certain objects from algebraic geometry. Two concepts that have been of prime importance in recent times in the ... -
Search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks in proton-proton collisions at √s= 13 TeV using CMS 2017 and 2018 data
The discovery of the Higgs boson has opened a new portal to search for Dark Matter(DM). Since DM does not interact in the CMS detector, searches rely on the missing transverse energy in association with a visible SM ... -
Correlations in multispecies asymmetric exclusion processes
The main aim of this thesis is to study the correlations in multispecies exclusion processes inspired by the research of Ayyer and Linusson (Trans. AMS., 2017) where they studied correlations in the multispecies TASEP on ... -
Electronic behavior of epitaxial thin films of doped rare-earth nickelates
Rare-earth nickelates (RENiO3), a family of transition metal oxides, exhibit a complex phase diagram involving electronic, magnetic, and structural phase transitions. While LaNiO3 remains paramagnetic, metallic down to ... -
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 ... -
Phonon anomalies in pyrochlores and 2D materials under extreme conditions: Insights from Raman spectroscopic studies
In solids, electrons do not behave as separate particles but instead interact intensely to form quasiparticles, which couple with other quasiparticles such as phonon, plasmon, and exciton to generate emergent quantum ... -
Aspects of Holography and Quantum complexity
We begin with the Principle of holography and the AdS/CFT correspondence. We begin our investigations by considering the Principle of Holography, at the level of codimension-1 screens. We argue that the mechanism of encoding ... -
Homogenization of PDEs on oscillating boundary domains with L1 data and optimal control problems
This thesis comprehensively studies the homogenization of partial differential equations (PDEs) and optimal control problems with oscillating coefficients in oscillating domains. After the introduction, the thesis is divided ... -
Superconducting qubit-based hybrid devices
Quantum technology has potential applications in many areas of science and engineering. Recently, there has been significant progress in developing hybrid quantum devices using a superconducting qubit platform. The hybrid ... -
Local Projection Stabilization Methods for the Oseen Problem
Finite element approximation of fluid flow problems with dominant convection exhibit spurious oscillations. To eliminate these nonphysical oscillations one needs to incorporate stabilizations that can curb the effect of ... -
Structural and Thermoelectric Studies of Sb2Te3 and Bi2Te3 Based Chalcogenide Alloys and Nanocomposites
Thermoelectricity is one of the potential solutions for the rapidly increasing energy demand. Thermoelectric generators can turn waste heat into usable energy. Due to their effectiveness in the 300 K to 500 K temperature ...
