I am theoretical condensed matter physicist involved in research and teaching physics. I investigate the diversity seen in physical properties of crystalline materials such as superconductors, topological insulators, multiferroics and other strongly correlated electron systems using mathematical methods that use quantum mechanical principals adapted to many body physics. Using analytical and numerical mathematical tools, I study the fundamental microscopic physics of materials and work in collaboration with experimentalists to decipher the physics behind new observations.

MY CURRENT RESEARCH
The bilayer Sr-327 compound shows a number of unexplained properties in its phase diagram. Long range anti-ferromagnetic state with Mn doping, magnetic field induced SDW state and nematicity are only some of the most interesting mysteries.
Weyl semi-metals are a new class of gapless topological phase that can be seen as a three dimensional analogue of graphene. They show unusual properties such as 'Fermi arcs', and chiral anomaly.
Vanadium Dioxide is a hotly debated compound in which the ability to control the metal-insulator transition provides the posibility for information storage. In collaboration with experimentalists performing Photoemmision spectroscopy and x-ray absorbtion experiments, we have developed a theory to show that the strained metallic VO_2 undergoes an "Orbital selective Mott transition". The work uses a recently developed slave spin theory.
