Introduction

Our research group specializes in semiconductor quantum optics and condensed matter physics, focusing on mesoscopic systems like two-dimensional materials, single-mode optical microcavities, and nanoscale electronic devices. Currently, we are exploring anisotropic excitons and their optical properties in ReS2, which shows potential for developing quantum non-Hermitian systems with non-trivial topology in exciton-polariton bands.

We are also dedicated to improving optical spectroscopy methods. Recently, we used optical vortex beams to study exciton dynamics in WSe2, opening new paths for exploring and understanding these complex systems.

  • This is the first paper from our lab, thoroughly investigating the anisotropic properties of ReS2
  • This is our lab’s first publication on tunable light-matter interaction observed in exciton-polaritons at the ReS2-DBR interface
  • This is among the most exciting results our Lab has published recently
  • This is our latest published work, where we showcase intriguing Resonant Raman phenomena in bare ReS2
  • The basis for our current work was established during PI’s postdoc in the quantum optics group of Prof. Nick Vamivakas at the University of Rochester
  • This work demonstrates that the relaxation of electronic spin can be affected by the significant orbital angular momentum carried by vortex beam light
  • Excitons in WSe2 experience valley relaxation when excited by a twisted light beam under near-resonant conditions
  • The beginning of our journey into Optoelectronics was marked by a piece of work from postdoctoral research in the group of Prof. Ritesh Agarwal at UPenn
  • A preview of the PI’s PhD thesis on electronic transport in individual InAs nanowires in the Quantum Electronics Lab supervised by Prof. Mandar M. Deshmukh, TIFR
