Spectroscopic and Diffraction Signatures of Quantum Spin Liquids, Skyrmion Lattices and Transition Metal Dichalcogenides at Low Temperatures and High Pressures
This thesis presents experimental as well as theoretical studies on several contemporary
systems like quantum spin liquids (QSLs), skyrmion lattices, and transition metal dichalcogenides
(TMDs) under extreme conditions ...
First Principles Study of Oxides : Bulk, Interfaces and Defects
In the recent years, oxides have been the focus of numerous theoretical and experimental
studies. This is because of a wide variety of exotic physical phenomenon,
such as multiferroicity, charge ordering, metal-insulator ...
Exploring carrier dynamics in van-der-Waals heterostructures with shot noise spectroscopy, thermoelectricity and opto-electronic study
In the last two decades, there has been tremendous progress in two-dimensional (2D) - material research. It is mainly
due to the availability of a large selection of 2D-materials and their van-der-Waals heterostructures. ...
Dielectric, Mechanical, Magnetic and Electromagnetic Shielding properties of Carbon nanomaterial embedded Polydimethylsiloxane composites
Composites are the advanced engineering materials invented by men with exceptional properties over traditional materials. These attractive and delightful materials are the result of developments in the area of engineering ...
Experimental Studies in Quantum Optics using Diode Lasers
This thesis discusses experimental studies with vapor cells containing rubidium (Rb) or
cesium (Cs) atoms. Transitions in the atoms (D1 and D2 lines) are accessed using diode
lasers. Experiments are performed at room ...
Mesoscopic Heat engines beyond the Limits of Thermodynamics
Despite the central role that Equilibrium thermodynamics has played in our understanding of many body systems, the underlying theoretical construct is strictly correct only in the ‘Thermodynamic Limit’. On the other hand, ...
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 ...
Rapid light sheet fluorescence microscopy for dynamic imaging of living organisms
The primary goal of this thesis is to develop a light sheet based microscopy system
that provides non-invasive images having high spatial and temporal resolution. The
fluorescence
microscopy has become an indispensable ...
Turbulent Mixing of Multiple-Passive-Scalars
We have studied the mixing of multiple forced passive scalars in 3D homogeneous
and isotropic turbulence. The trends of the structure functions for a
single scalar, although not very well resolved, seem to be similar to ...
Physics and application of charge transfer in van der Waals heterostructures
Since the discovery of graphene, the field of 2D materials has garnered massive interest from a materials science, basic physics and device application point of view. This
results from the diverse range of electronic and ...
