Impact of Disorder and Topology in Two Dimensional Systems at Low Carrier Densities
(2018-02-15)
Two dimensional (2D) systems with low carrier density is an outstanding platform for studying a wide spectrum of physics. These include both classical and quantum effects, arising from disorder, Coulomb interactions and ...
Engineering Plasmonic Interactions in Three Dimensional Nanostructured Systems
(2018-02-08)
Strong light matter interactions in metallic nanoparticles (NPs), especially those made of noble metals such as Gold and Silver is at the heart of much ongoing research in nanoplasmonics. Individual NPs can support collective ...
Investigations on Photophysical Properties of Semiconductor Quantum Dots (CdxHg1-xTe,Ag2S) and their Interactions with Graphene Oxide, Organic Polymer Composites
(2018-02-07)
The motivation of this thesis is to understand the physical properties of semiconductor quantum dots (QDs) and to get insight on the basic physics of charge separation in composites made from QDs with graphene oxide ...
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 ...
Hyperfine Structure-Measurement in Alkali-metal Atoms and Ytterbium Atom
(2018-02-15)
Atomic precision measurements provide a strong testing ground for new theoretical ideas and fundamental laws of physics. Measurement of the Lamb shift in the hydrogen atom is one of the best examples towards this -it ...
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 ...
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 ...
Role of Excess Fe in Pristine and Substituted Fe Chalcogenide Superconductors
(2018-03-02)
Fe chalcogenides : The discovery of superconductivity in Fe based compounds trig-
gered an intense research activity in this field with significant importance given to
material synthesis. As a result, numerous materials ...
Development of a Spin-Polarized Low Energy Electron Diffraction System and Investigation on Spin-Orbit and Exchange Interactions on Ir(100) and Ultrathin Fe(100) Grown on Ir(100)
(2018-02-28)
Spin-polarized electron beam has not yet been produced from an unpolarized electron beam using Stern-Gerlach type spin filter, because of the Lorentz force and Heisenberg uncertainty principle. At present, electron spin ...
The Many Facets of Variabilities in X-ray Binaries
(2018-02-28)
More than half a decade of X-ray astronomy with various balloon borne and space orbiting X-ray instruments, have led to discoveries and detailed studies of X-ray binaries. An important property of X-ray binaries is intensity ...
