Study on optical and electrical transport properties of twisted bilayer transition metal dichalcogenides
Van der Waals (vdW) heterostructures, where dissimilar atomically thin vdW crystals are vertically assembled, have initiated a new paradigm to create flexible multifunctional devices. Despite the weak nature of vdW ...
Quantized heat flow probing thermal equilibration and edge structures of quantum Hall phases in graphene
In condensed matter physics, usually, phases are described using Landau’s approach, which characterizes the phases in terms of underlying symmetries that are spontaneously broken. Over the past few decades, a different ...
An experimental study on thermoelectric transport at van der Waals interfaces
When two planar atomic or molecular layers are brought to sub-nanometer proximity,
they form a van der Waals interface because the van der Waals force forms the dominant
attractive force between them. The van der Waals ...
Thermodynamics and Statistical mechanics of loops: A Monte Carlo study
Thermodynamics and Statistical Mechanics of Multi-colored Loop models in three dimensions: A Monte-Carlo study.

ABSTRACT
A perfectly crystalline solid is a regular ...
Exploration of multiferroicity, emergence of exchange bias effect and glassy magnetism in doped hexagonal rare-earth manganites
In recent days, the need for device miniaturization has led to immense research activities in the field of material science. It has become essential to discover and design new materials or to modify the existing materials ...
Study of the Thermoelectric Properties of RxCo4Sb12 (R=In, Ba) with InSb/GaSb Nano Inclusions
Almost 80% of the world’s energy needs depend on oil, coal and natural gases. Use of natural gases, fossil fuels emit a large amount of CO2 to the earth’s atmosphere, which causes the greenhouse effect and results in an ...
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 ...
Electrical transport in 3-dimensional topological insulators
Topological insulators (TI) are a new class of materials in which gapped bulk states coexist with gapless surface-states having linear energy-momentum dispersion relation protected by time-reversal symmetry. These ...
Dynamics and Organization of Passive and Magnetically Driven Colloids Under Optical Confinement
The physics of confined systems of interacting particles has been a subject of active research for more than a century. Such systems are ubiquitous in nature - examples include petroleum in porous rocks, cytoplasm in ...
Correlation, superconductivity, and topology in twisted and untwisted layered systems
This thesis is an effort to understand some of the interesting features induced by strong correlation - superconductivity, topology, non-Fermi liquid (NFL) in two dimensional (2D) layered materials. 2D layered materials ...
