Numerical Studies Of Slow Dynamics And Glass Transition In Model Liquids
(2009-12-16)
An increase in the co-operativity in the motion of particles and a growth of a suitably defined dynamical correlation length seem to be generic features exhibited by all liquids upon supercooling. These features have been ...
Elasticity And Structural Phase Transitions Of Nanoscale Objects
(2015-12-14)
Elastic properties of carbon nanotubes (CNT), boron nitride nanotubes (BNNT), double stranded DNA (dsDNA), paranemic-juxtapose crossover (PX-JX) DNA and dendrimer bound DNA are discussed in this thesis. Structural phase ...
Phases, Transitions, Patterns, And Excitations In Generalized Bose-Hubbard Models
(2016-09-12)
This thesis covers most of my work in the field of ultracold atoms loaded in optical lattices. This thesis can be divided into five different parts. In Chapter 1, after a brief introduction to the field of optical lattices ...
Mesophases Of Active Matter : Translational Order, Critical Rheology And Electrostatics
(2016-04-26)
This thesis consists of research work in the broad area of soft condensed matter theory with a focus on active matter. The study of long wavelength, low frequency collective behavior of active particles (bacterial suspensions, ...
Transport In Quasi-One-Dimensional Quantum Systems
(2011-04-01)
This thesis reports our work on transport related problems in mesoscopic physics using analytical as well as numerical techniques. Some of the problems we studied are: effect of interactions and static impurities on the ...
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 ...
Ion Assisted Deposition Of HfO2 Thin Films For CMOS Gate Dielectric Applications
(2013-09-13)
The scaling down of Complementary Metal Oxide Semiconductor (CMOS) transistors to sub-100nm requires replacement of conventional Silicon dioxide layer with high dielectric constant (K) material for gate dielectric. Among ...
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, ...
