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. ... -
