     Educational Background/Employment:
    • (2019) Condensed Matter Physics, Univ. of Utah
    • (2015) Physics, Indian Institute of Science Education and Research, Bhopal, India
    • Employment:
      • 2019-present Postdoctoral Research Associate, Los Alamos National Laboratory, NM, USA.

    Research Interests:

    • Light matter interaction in Topological insulators: I am mainly interested in the graphene family materials, such as silicone, germanene, plumbene, and stanene. The topological phases can be externally controlled by means of an external field or circularly polarized laser. I am investigating the effect of topologically non-trivial phase on the nonlinear optical response.
    • Spin-orbit coupling: I am also interested in various spin-orbit effects in materials and how the interplay between spin-orbit effect and Zeeman splitting unlocks novel phenomena in quantum transports.
    • Integrability in multistate Landau-Zener model: Another interesting area of my research is to look for integrability in quantum systems with multiple level crossings.
