Transport and criticality in topological systems and spin models
This thesis presents work done on transport in topological insulators and graphene-based systems, and quantum criticality in one- and two-dimensional spin
models. In particular we study the following: transport on surfaces ...
Edge States and Effects of Disorder in Finite Graphene Sheets
The thesis endeavours to theoretically understand electronic properties of nite trapezoidal shaped graphene sheets, and understand zero energy edge states. The motivation for this thesis is recent experimental work at Low ...
Statistics of Conductance Fluctuations in 2D systems
Study of 2D materials is interesting due to the various phase transitions observed
in these materials. I shall present the results obtained in the study of phase transi tions in three different 2D material systems – ...
Investigation of inter-layer charge transfer process in optically excited graphene and transition metal dichalcogenide-based heterostructures
Light-matter interaction of two-dimensional (2D) materials and their van der Waals hybrids have gained significant interest in the past few years as they offer an intriguing platform for studying fundamental physical ...
