High-Resolution Spectroscopy in Atoms Using Coherent Control
(2017-10-26)
The subject of this thesis is the study of coherent interaction of light with matter (atoms) to improve the precision measurements and techniques. Special attention is drawn to get the narrow subnatural electromagnetically ...
Direct Numerical Simulations of Fluid Turbulence : (A) Statistical Properties of Tracer And Inertial Particles (B) Cauchy-Lagrange Studies of The Three Dimensional Euler Equation
(2017-11-09)
The studies of particles advected by tubulent flows is an active area of research
across many streams of sciences and engineering, which include astrophysics,
fluid mechanics, statistical physics, nonlinear dynamics, and ...
Direct Measurement of Itinerant Magnetism & Interface States in Semiconductors using Time-varying Magnetic Fields
(2017-11-28)
Magnetism in a solid | dia, para, ferro, or of other forms | originates majorly from its electrons; one could, infact, ignore the nuclear contribution. There are two types of electrons in a solid: bound, and free (also ...
Experimental Investigation of Multielectron Bubbles in Liquid Helium
(2017-11-28)
Multielectron bubbles (MEBs) are micron sized cavities in liquid helium that contain electrons confined within a nanometer thick layer on the inner surface of a bubble. These objects present a rich platform to study the ...
Investigation of Nonlinearities in Graphene Based NEMS
(2017-10-05)
Nanoelectromechanical systems (NEMS) have drawn considerable attention towards several sensing applications such as force, spin, charge and mass. These devices due to their smaller size, operate at very high frequencies ...
Effect of Antimony Doping in Iron Chalcogenides
(2017-11-27)
This thesis is organized in to six chapters. The contents of each chapter are briefly summarized in the following sections.
Chapter 1 introduces different Fe-based superconductors. Within a very short span of their ...
Collective Behaviour of Confined Equilibrium And Non Equilibrium Soft Matter Systems
(2017-11-09)
Due to their diversity, soft matter systems provide a convenient platform to study a variety of physical phenomena like phase transitions and collective motion. Encompassing a wide range of equilibrium and non-equilibrium ...
Polarized Line Formation In Turbulent And Scattering Media
(2010-10-13)
This thesis is devoted to improve our knowledge on the theory of polarized line formation in a magneto-turbulent medium, and in a scattering dominated magnetized medium, where partial redistribution (PRD) effects become ...
Studies Of Electronic, Magnetic And Entanglement Properties Of Correlated Models In Low-Dimensional Systems
(2015-09-04)
This thesis consists of six chapters. The first chapter gives an introduction to the field of low-dimensional magnetic and electronic systems and relevant numerical techniques. The recent developments in molecular magnets ...
Phases, Transitions, Patterns, And Excitations In Generalized Bose-Hubbard Models
(2016-09-12)
This thesis covers most of my work in the field of ultracold atoms loaded in optical lattices. This thesis can be divided into five different parts. In Chapter 1, after a brief introduction to the field of optical lattices ...
