Magnetic and Magnetotransport Studies in Transition Metal Oxides : Role of Competing Interactions
(2018-04-12)
There was a fame time for silicon in condensed matter physics, then the graphene era came and now topological insulators are gaining lot of attention, but magnetism in condensed matter physics has remained always fascinating ...
Phenomenological Theory Of Superconductivity And Low-Energy Electronic Spectra In The High-Tc Cuprates
(2013-09-11)
Condensed matter physics is a rapidly evolving field of research enriched with the synthesis of new materials exhibiting a bewildering variety of phenomena and advances in experimental techniques. Over the years, discoveries ...
Some Unconventional Phases And Phase Transitions In Condensed Matter : Spin-Nematics, Spin-Liquids, Deconfined Critical Points And Graphene NIS Junctions
(2013-07-19)
Condensed matter physics provides us with an opportunity to explore a large variety of systems with diverse properties. Central to the understanding of these systems is a characterization of the nature of their ground ...
Optical And Structural Investigations Of Defects In CdZnTe(Zn ~ 4%) Crystals
(2013-06-12)
The CdTe family members (in particular CdZnTe) remain the substrate of choice for epitaxial growth of HgCdTe for use in high performance infrared (IR) detectors and focal plane arrays. This is the case despite advances in ...
Magnetisation, Phases & Phase Transitions in Frustrated and Unfrustrated XY Model
(2018-02-23)
Through our whole work we study the XY model with all its entirety, a particular spin model where spins are confined in a plane. We try to bring out a good understanding of this model with all different types of phases and ...
Flow Induced Instabilities, Shear-Thickening And Fluctuation Relations In Sheared Soft Matter
(2016-09-09)
In day to day life we encounter many different materials which are intermediate between crystalline solids and simple liquids that include paints , glues , suspensions, polymers, surfactants, food and cosmetic products and ...
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 ...
Shear Induced Transitions In Mixed Surfactant Systems And Anisotropic Colloids
(2017-06-12)
This thesis deals with the non-equilibrium phenomena under shear observed mainly in bilayer forming liquid crystalline phases of mixed surfactant systems, anisotropic colloidal dispersions as well as Langmuir monolayers ...
Electron Spin Resonance And Optical Studies On The Conducting Polymer Polyaniline
(2011-07-11)
For every phenomenon found in inorganic materials, organic counterparts have been found in the last 50 years. The discovery of metallic conductivity in the inorganic conjugated polymer (SN)x was a forerunner to the discovery ...
Phase Behaviour & Dynamics Of An Agitated Monolayer Of Granular Rods
(2010-10-05)
In this thesis we have explored the no equilibrium phase behavior and dynamics of an agitated monolayer of macroscopic rod-like particles. The main objective of this thesis was to highlight the ways in which even the ...
