Origin of Instability and Plausible Turbulence in Astrophysical Accretion Disks and Rayleigh-stable Flows
(2017-12-10)
Accretion disks are ubiquitous in astrophysics. They are found in active galactic nuclei, around newly formed stars, around compact stellar objects, like black holes, neutron stars etc. When the ambient matter with ...
Quantum Simulations by NMR : Applications to Small Spin Chains and Ising Spin Systems
(2017-11-22)
Quantum simulations, where controllable quantum systems are used to simulate other quantum systems, originally proposed by Richard Feynman, are one of the most remarkable applications of quantum information science. Compared ...
Continuous Beam of Laser-Cooled Ytterbium Atoms for Precision Measurements
(2017-11-22)
What if an elementary particle such as an electron had an intrinsic electric dipole moment (EDM)? Existence of such an EDM would be an indication of time-reversal symmetry
violation in the laws of Physics. The Standard ...
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 ...
