Introducing Prof. Sai Vinjanampathy

We are delighted to welcome Professor Sai Vinjanampathy to the IIT Bombay family. He joined the Department of Physics of IIT Bombay last year.

He completed his B.Sc. from Jain College (Madras University) and did his M.Sc. from IIT Madras. He went to the Louisiana State University for his PhD (2010) in Quantum Information Theory, Quantum Control, Quantum Thermodynamics. He completed his Post Doctorial Degree at UMASS form 2010-2012.He worked as Research Fellow at Centre for Quantum Technology, National University of Singapore 2012-July 2016 and is continuing as Visiting Research Fellow at the same.

His research interest is in the field of quantum thermodynamics, which is basically the study of non-equilibrium statistical studies when N is not large, such systems find relevance in nano-scale technology.

His plan at IIT Bombay is to work on various aspects of quantum control and thermodynamics. He is working on several problems of optimising "small N" analogues of thermodynamically interesting tasks. For instance, he has interested in how to best optimise engine performance. Optimising power and efficiency are two examples of a set of natural questions that arise in the study of engines that are perturbed from equilibrium. He is working on such questions in the deep non-equilibrium regime and is involved in generating protocols for optimising quantum engines, quantum batteries etc 

A naturally connected topic is the control and optimisation of phase transitions in many-body quantum systems. The connection is obvious since physical engines have to be implemented in physical systems, such as spin chains or cold atomic systems. He is interested in optimised protocols for controlling dynamical properties of such many body quantum systems. For example, a recent interest of his is in dynamical phase transitions in open quantum systems.
