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 ...
Phonon Anomalies And Phase Transitions In Pyrochlore Titanates, Boron Nitride Nanotubes And Multiferroic BiFeO3 : Temperature- And Pressure-Dependent Raman Studies
(2013-09-13)
This thesis presents experimental and related theoretical studies of pyrochlore titanate oxides, boron nitride nanotubes, and multiferroic bismuth ferrite. We have investigated these systems at high pressures and at low ...
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 ...
Role Of Surface And Inter-particle Spacing On Optical Properties Of Single And Hybrid Nanoparticle Assemblies
(2013-07-03)
Optical properties of nanoscopic materials have been intensively perused over last couple of decades due to their tunable optical properties. Recent interests in this field have been mainly focused on the preparation of ...
Origin Of The Extragalactic Gamma-Ray Background
(2013-10-01)
It is evident that the origin of EGRB is not well established. In this thesis I examine the unresolved discrete origin of EGRB. The contribution from normal galaxies, starburst galaxies and AGNs to the EGRB is examined. ...
Numerical Study Of The Complex Dynamics Of Sheared Nematogenic Fluids
(2013-07-17)
In this thesis, we have tried to explain the regular and irregular(chaotic) dynamics of worm like micellar solutions on applying shear, through a detailed study of the equation of motion of a nematic order parameter tensor ...
Studies Of Diffuse Ultraviolet Radiation
(2013-10-07)
Ever since the first observations of diffuse ultraviolet radiation by Hayakawa et al. (1969) and Lillie & Witt (1976), there has been an effort to understand its distribution and its origin. Unfortunately, because of the ...
Crystal Structure Of Mycobacterium Tuberculosis Histone Like Protein HU And Structure Based Design Of Molecules To Inhibit MtbHU-DNA Interaction : Leads For A New Target. Structure Aided Computational Analysis Of Metal Coordinated Complexes Containing Amino Acids And Organic Moieties Designed For Photo Induced DNA Cleavage
(2015-08-17)
In bacteria, nucleoid associated proteins (NAPs) represent a prominent group of global regulators that perform the tasks of genome compaction, establishing chromosomal architecture and regulation of various DNA transactions ...
Pulsed Laser Ablated Dilute Magnetic Semiconductors and Metalic Spin Valves
(2018-04-02)
Spintronics (spin based electronics) is a relatively new topic of research which is important both from the fundamental and technological point of view. In conventional electronics charge of the electron is manipulated and ...
