Complex magnetism and structural phase transition in correlated oxide systems
Perovskite and pyrochlore materials constitute a profoundly intriguing and extensively studied family owing to their diverse magnetic and structural properties. we thoroughly explored the structure and magnetism of the ... -
Investigation into flux-coupled electromechanical devices
Cavity optomechanical systems involve modulation of the resonance frequency of an optical cavity by the motion of a mechanical resonator. These systems are used to control and manipulate mechanical motion down to the quantum ... -
On two complex Hessian equations and convergence of corresponding flows
This thesis consists of three parts. Two important complex Hessian equations are studied on certain compact K\"ahler manifolds from different perspectives. The first one is the {\em J-equation} introduced independently by ... -
On existence and regularity of some complex Hessian equations on Kahler and transverse Kahler manifolds
The thesis consists of two parts. In the first part of the thesis, we classify the convergence behaviour of rotationally symmetric solutions to the modified J-flow on the blow-up of the complex projective space at a ... -
On regular subalgebras of symmetrizable Kac-Moody algebras and related combinatorics
In this thesis, we study two aspects of Kac-Moody algebras. One is to understand the subalgebras that can be embedded inside a Kac-Moody algebra as subalgebras generated by real root vectors. The other one is to explicitly ... -
Military applications of Fiber Bragg Gratings
Fiber Bragg gratings (FBGs) are widely used in sensing technologies due to their compact size, distributed sensing capability, immunity to electromagnetic interference, and ability to measure various physical parameters. ... -
Existence and implications of positively curved metrics on holomorphic vector bundles
This thesis is divided into two parts. In the first part, we study interpolating and uniformly flat hypersurfaces in complex Euclidean space. The study of interpolation and sampling in the Bargmann-Fock spaces on the complex ... -
Realization of Type-II Dirac Semi-metal in NiTe2 using Structural, Electrical and Magnetic Investigation
Dirac semimetal (DSM) is a topological semi-metal with a fourfold degenerate linear band crossing in the bulk, in the presence of time-reversal symmetry and inversion symme- try, exhibiting nontrivial spin-momentum locking ... -
Nanoscale spatial and temporal response of lipid membranes interacting with biomolecules and nanoparticles
The cell membrane is the first point of interaction whenever any external biomolecule or nanoparticle encounters a cell. Thus the nature of interactions between the cell membrane and various proteins, nanoparticles, and ... -
Design and Development of Fiber Bragg Grating Sensor Devices for Aerospace Applications
Optical sensors are becoming increasingly popular and gradually replacing electrical sensors due to their faster response, higher sensitivity, immunity to electromagnetic interference and electrical sparking. The advancements ... -
Search for Long-Lived Particles at High Luminosity Large Hadron Collider and Beyond
Despite extensive searches, clear indications of new physics beyond the Standard Model (BSM) remain elusive. Traditionally, experimental searches at the Large Hadron Collider (LHC) during Phase I and phenomenological studies ... -
Planar tunneling in twisted moire heterostructures
Quantum tunneling is a phenomenon that has excited physicists for many decades. With the ability to exfoliate two-dimensional (2D) materials from the bulk, including graphene, hexagonal boron nitride (hBN), and transition ... -
Single molecule based Super-Resolution Microscopy for disease biology
Advances in single-molecule imaging and super-resolution microscopy have revolutionized the field of cell biology, offering unprecedented insights into complex biological processes at the nanoscale. In this thesis, we ... -
Study of the Effect of Ag-Addition and Double Substitution (Te/Gd and Se) on the Thermoelectric Properties of Cu12Sb4S13 Tetrahedrite
Non-renewable energy sources, such as natural gas, coal, and oil, supply over 80% of the world’s energy demands. The earth’s atmosphere is heavily polluted with CO2 generated from fossil fuels and natural gases, raising ... -
Single Molecule Based Spatio-temporal Super-resolution Microscopy for Visualizing Single Molecule Dynamics in Cellular System
Over the last decade, single-molecule localization microscopy (SMLM) has developed into a set of powerful techniques that have improved spatial resolution over diffraction-limited microscopy and demonstrated the ability ... -
Geometry of normed linear spaces in light of Birkhoff-James orthogonality
In this thesis, we have tried to understand the geometry of normed spaces in the light of Birkhoff-James orthogonality. Using the first two chapters to give introductory notes and to establish relevant notations and ... -
Some investigations into algebraic and geometric properties of Feynman integrals and related topics
We describe our investigations into various formal properties of Feynman integrals and of scattering amplitudes obtained from studying algebraic structures. There are variety of ways to study these properties. Out of which, ... -
The Cahn-Hilliard-Navier-Stokes Framework for Multiphase Fluid Flows: Laminar, Turbulent, and Active
The Cahn-Hilliard-Navier-Stokes (CHNS) framework has found extensive applications, across diverse length and time scales, for multi-phase flows. In this thesis, we demonstrate that this framework offers a robust theoretical ... -
Some Aspects of Weighted Kernel Functions on Planar Domains
The broad aim of this thesis is to study some aspects of weighted kernel functions. In particular, this thesis has been driven by three principal goals: First, to study the boundary behaviour of weighted Bergman kernels. ...
