Charge Transport and Photo-Physical Studies in Conjugated Polymers, Hybrid Nanocomposites and Devices
(2017-12-12)
The main motivation of this thesis is derived from the fact that physics of disordered systems like conjugated polymer has yet not achieved as concrete understanding as ordered and crystalline systems such as inorganic ...
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 ...
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.

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 ...
Crawling, Waving, Spinning : Activity Matters
(2017-12-12)
This thesis has been concerned with a few problems in systems driven at the scale of particles. The problems dealt with here can be extended and elaborated upon in a variety of ways. In 2 we examine the dynamics of a fluid ...
Some Studies of Statistical Properties of Turbulence in Plasmas and Fluids
(2017-12-12)
Turbulence is ubiquitous in the flows of fluids and plasmas. This thesis is devoted to studies of the statistical properties of turbulence in the three-dimensional (3D) Hall magnetohydrodynamic (Hall-MHD) equations, the ...
Numerical Studies of Problems in Turbulence : 1) Fluid Films with Polymer Additives; 2) Fluid Films with Inertial and Elliptical Particles; 3) Scaled Vorticity Moments in Three- and Two-dimensional Turbulence
(2017-11-30)
In this thesis we study a variety of problems in fluid turbulence, principally 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 Chapter ...
Study of Phase Transitions in Two Dimensions using Electrical Noise
(2017-11-21)
It is well known from Mermin-Wagner theorem that a two dimensional(2D) system with continuous symmetry can have no long-range order at finite temperature. However such systems can undergo a transition from a low temperature ...
