A Study of Superbubbles in the ISM : Break-Out, Escape of LYC Photons and Molecule Formation
(2018-02-16)
Multiple coherent supernova explosions (SNe) in an OB association can produce a strong shock that moves through the interstellar medium (ISM). These shocks fronts carve out hot and tenuous regions in the ISM known as ...
Impact of Disorder and Topology in Two Dimensional Systems at Low Carrier Densities
(2018-02-15)
Two dimensional (2D) systems with low carrier density is an outstanding platform for studying a wide spectrum of physics. These include both classical and quantum effects, arising from disorder, Coulomb interactions and ...
Engineering Plasmonic Interactions in Three Dimensional Nanostructured Systems
(2018-02-08)
Strong light matter interactions in metallic nanoparticles (NPs), especially those made of noble metals such as Gold and Silver is at the heart of much ongoing research in nanoplasmonics. Individual NPs can support collective ...
Hyperfine Structure-Measurement in Alkali-metal Atoms and Ytterbium Atom
(2018-02-15)
Atomic precision measurements provide a strong testing ground for new theoretical ideas and fundamental laws of physics. Measurement of the Lamb shift in the hydrogen atom is one of the best examples towards this -it ...
The Cosmic Population of Extended Radio Sources : A Radio-Optical Study
(2017-09-27)
This thesis presents studies of cosmic populations of extragalactic radio sources. The problems selected for this thesis are 1) the derivation of constraints on the emergence of new sub-mJy populations at flux density below ...
Mixed Alkali Effect in Oxyfluoro Vanadate Glasses And The Effect of Rare Earth Ions on Oxyfluoro Tellurite Glasses - A Spectroscopic Study
(2017-09-20)
The main motivation of this thesis is to study the long standing problem of mixed alkali effect (MAE) in oxyfluro vanadate glass systems from the point of view of structural arrangement and to investigate the effect of two ...
Nature Of Criticality, Structuring, And Phase Behavior Of Complex Fluids
(2009-03-04)
This thesis is mainly concerned with some important properties of complex fluids, and how these properties are influenced by structures in the nano/mesoscopic scale. Short-range assembly of the constituent molecules results ...
Cahn-Hilliard-Navier-Stokes Investigations of Binary-Fluid Turbulence and Droplet Dynamics
(2017-12-10)
The study of finite-sized, deformable droplets adverted by turbulent flows is an active area of research. It spans many streams of sciences and engineering, which include chemical engineering, fluid mechanics, statistical ...
Particles and Fields in Superfluid Turbulence : Numerical and Theoretical Studies
(2017-12-16)
In this thesis we study a variety of problems in superfluid turbulence, princi-pally in two dimensions. A summary of the main results of our studies is given below; we indicate the Chapters in which we present these.
In ...
A Study of Electrical Transport and 1 / f Noise in Topological Insulators
(2017-12-10)
The recent discoveries of topological insulators (TI) has opened a new realm for study¬ing topological systems and exploring the exotic properties they offer. The in-built topological protection against direct backscattering ...
