I have been working mainly in (theoretical) condensed matter physics for the last several
years, although my PhD
and early career was in the field of (theoretical ) high energy
particle physics.
In the last few years, my research work has mainly been in the field
of mesoscopic physics in low dimensions and topological quantum matter
We are interested in edges formed either naturally or by engineering potentials in
the bulk of the sample, by different techniques like gating or by shining light (Floquet).
(a) Quantum Hall edge reconstruction. -
Here, we have studied and continue to study
edge reconstruction in the presence of interactions involving spinful edge modes in the integer
quantum Hall regime
(b) Engineered edges in single and bilayer graphene and silicene, using Floquet or gating.
The idea is to explore Luttinger liquid physics including the Kondo effect using engineered wires.
We are also studying edge reconstruction due to interactions in these systems
(a) We have been studying electrical and thermal conductances through junctions of WSM phases.
(b) We have also been looking at band structures and surface states of twisted WSM junctions.
Helical edge states of topological insulators
Higher order topological insulators
Anyons, Majorana modes and parafermions .
We have been studying various geometries for the detection of Majorana zero modes
and parafermions
