New approaches to study quantum light-matter interaction – An overview

Dr Himadri Shekhar Dhar

IIT Bombay
Synopsis:
From quantum computation to communication, design of quantum devices and peripheral technology relies strongly on the interaction of light with matter. This requires not only modelling these interactions at the microscopic level but also seeking appropriate solutions at different operational regime. In this talk, we informally look at a few approaches that can be used to study such light-matter interactions. These range from rate equations, cluster state expansion and quantum trajectories to study photon condensates to tensor-network methods to design spin-ensemble based quantum memories.
Biography:
Himadri is an assistant professor at the Indian Institute of Technology, Bombay. Prior to this, he was a Postdoc at Imperial College, London (2019-21) and a Lise-Meitner Fellow at TU Wien in Vienna, Austria (2016-2018). His field of research is the theoretical study of quantum dynamics at the interface of quantum information theory, quantum optics and many-body physics. In the last few years, his work has focussed on how tools from many-body physics and open systems can be harnessed to study light-matter interaction that can be used to implement quantum information protocols and devices and also study basic non-equilibrium dynamics.
