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.

Electrical Transport in the Hybrid Structures of 2D Van Der Waals Materials and Perovskite Oxide
(2018-01-01)
Perovskite oxides have provided a wide variety of exotic functionalities based on their unique physical and chemical properties. By combining different perovskite oxides, interesting physical phenomena have been observed ...
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 ...
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 ...
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 ...
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 ...
Modelling, Fabrication and Characterization of HgCdTe Infrared Detectors for High Operating Temperatures
(2018-02-23)
In this work, we have designed, simulated, fabricated and characterized homojunction Hg1-xCdxTe detector for high operating temperature in the MWIR region. The IR photon detectors need cryogenic cooling to suppress thermal ...
Growth and Physical Properties of Biaxial Nonlinear Optical Crystals of Ascorbic Acid Family
(2018-02-26)
Saccharides, a class of organic materials, are potential candidates for nonlinear optical applications. Ascorbic acid is a sugar acid and is classified as a monosaccharide. The molecule of ascorbic acid has two chiral centers ...
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.

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 ...
