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 ... -
Spatial Encoding NMR : Methods and Application to Relaxation Measurements, Dissolution Monitoring and Ultrafast NMR
(2018-02-06)Discrete and Continuous spatial encoding methods are described with details of understanding principles and practical implications. Step by step experimental op- timization procedure of these methods to achieve slice ... -
Spin Hall Effect Mediated Current Induced Magnetization Reversal in Perpendicularly Magnetized Pt/Co/Pt Based Systems
(2018-02-08)In the present thesis, magnetization reversal in both out-of-plane and in-plane magnetized thin lms and in devices fabricated out of those lms are explored. Pt/Co/Pt stacks with ultrathin Co layer were in-estimated initially ... -
Studies of X-Ray Transients and a Future X-Ray Sky Monitor
For this thesis we studied X-ray transients. In addition we also studied some methods to study these transients, both observationally and in terms of the instrument used. The first transient studied is a black hole binary ... -
Study of Dynamics, Thermal and Rheological Properties of Polymer Grafted Nanoparticle-polymer Blend
We studied dispersion state and dynamics of polymer grafted nanoparticle in photopolymer matrix nanoparticle-polymer blend- and their thermal and rheological properties. While thinking about a nanoparticle-polymer blend, ... -
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 ... -
Study of Light-Matter Interaction at the Nanoscale with Quantum Dots in Photonic and Plasmonic Metamaterials
(2017-11-28)Optical properties of nanoscopic materials have been intensively pursued over last couple of decades due to their tunable optical properties. Recent interests in this field have been mainly focused on the preparation of ... -
Study of Optical Properties of Semiconductor Quantum Dot Based Hybrid Nano Assemblies
(2017-11-28)Over the last few decades, a vast research is going on, to study the optical properties of the nano particles i.e., metal and semiconductors thoroughly. Till date most of the optical studies are based on single particle ... -
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 ... -
Ultra Cold Fermions : Dimensional Crossovers, Synthetic Gauge Fields and Synthetic Dimensions
(2018-02-06)Ultracold atomic systems have provided an ideal platform to study the physics of strongly interacting many body systems in an unprecedentedly controlled and clean environment. And, since fermions are the building blocks ...
