Spectro-temporal signatures of accretion flows around Galactic Black Holes
A system of two stars in which one is a black hole (BH) is referred to as a black hole
binary (BHB). In a BHB, it is possible to have mass transfer from the secondary star
(companion star) to the primary black hole. ...
Study of Thermoelectric Transport Properties of Doped and Vacancy Induced BiCuSeO
About 70% of the heat generated for energy production is wasted and thermoelectric generators can capture this waste heat and convert it into useful electricity. The stability at high temperature in the ambient atmosphere ...
Design and Analysis of Surface Acoustic Wave Filters
The generation and detection of surface acoustic waves (SAWs)
using interdigital transducers (IDTs) on a piezoelectric surface have
been used to produce many high performance Band Pass Filters.
This thesis focuses on ...
Exploring Electron Bubbles in Liquid Helium using Cavitation
An electron entering liquid helium experiences a repulsive potential of 1 eV. This originates in the interaction between the injected electron and electrons of the closed shells of helium atoms through Pauli exclusion ...
Topological Phases, Majorana Modes, Dynamics and Transport in One-Dimensional Systems
This thesis presents work done on topological phases, Majorana modes, dynamics and
transport in various system like the Kitaev models in one and two dimensions and systems
with junctions of a p-wave superconductor and ...
Electron Paramagnetic Resonance and Magnetic Studies of Certain Doped Rare Earth Manganites
Doped rare-earth manganites with the general formula T1xDxMnO3 where `T' is a trivalent
rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion,
e.g Ca2+; Sr2+;Ba2+ etc. display various ...
Lessons for Gravity from Entanglement
One of the recent fundamental developments in theoretical high energy physics is the AdS/CFT
correspondence [1, 2, 3, 4] which posits a relationship between Quantum Field Theories (QFT)
in a given dimension and String ...
Fluctuations in quantum transport in topological insulators
Topological insulators (TIs) belong to a new class of materials characterized by linear
surface states, which emerge in the bulk band gap due to non-trivial topology of the band
structure. These surface states have various ...
Design, Fabrication and Characterization of Metal Oxide Semiconductor Based MEMS Gas Sensors for Carbon Monoxide Detection
In recent years, intense efforts have been made towards the development of miniaturized gas-sensing devices for hazardous gas detection. Carbon monoxide, which is a result of incomplete combustion, is a colourless, odourless, ...
Coulomb drag to thermopower response in dimensionally mismatched InAs nanowire-Graphene heterostructures and anisotropic noise in ReS2
Coulomb drag technique is a notable tool for probing electron-electron interaction in double-layer systems, where the momentum and energy transfer from one layer to the other layer as a result of Coulomb interaction. In ...
