Glassy Dynamics in Active Matter
There has been much interest in the glassy dynamics of living systems at the scales
of subcellular structures, cells and tissues. This has motivated theoretical studies on
the approach to glassy behaviour in dense systems ...
Effects of Strong Electron-Electron Correlations on Band Insulators in Equilibrium and Non-Equilibrium
In this thesis, several aspects of correlation effects in band insulators that were hitherto not addressed, both in equilibrium and non-equilibrium, are studied using the Ionic Hubbard model (IHM) at half-filling and ...
A Theoretical Study of Thermoelectric Effect for Cross-plane Transport Across Twisted Bilayer Graphene
The thermoelectric effect and the linear response theory is one of the most studied areas in condensed matter physics. In the last few years, the study of Van Der Waals heterostructure has become one of the most promising ...
Studies of Diamagnetism and Thermoelectric Transport in High Temperature Superconductors and Graphene
Using a recently proposed Ginzburg-Landau-like free energy functional due to Banerjee et al. Phys. Rev. B 83, 024510 (2011) we calculate the fluctuation diamagnetism of high-T c superconductors as a function of doping, ...
Dynamics of Glass-Forming Liquids and Shear-Induced Grain Growth in Dense Colloidal Suspensions
(2018-06-19)
The work presented in this doctoral thesis employs colloidal suspensions to explore key open problems in condensed matter physics. Colloidal suspensions, along with gels, polymers, emulsions and liquid crystals belong to ...
Confinement, Coarsening And Nonequilibrium Fluctuations In Glassy And Yielding Systems
(2016-02-17)
One of the most important and interesting unsolved problems of science is the nature of glassy dynamics and the glass transition. It is quite an old problem, and starting from the early20th century there have been many ...
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 ...
