Title: Quantum thermodynamic resources--- from coherence to non-Markovianity

Speaker: Dr, Varun Narasimhachar, Nanyang Technological University, Singapore

Abstract: A thermodynamic resource is a physical system that can fuel an engine to perform useful work. The history of thermodynamics has been one of continual expansion in the variety of such resources: while the first engines could only be fueled by temperature gradients, later developments enabled engines powered by any form of free energy, including pure information. In this seminar, we will present a glimpse of our work where we characterized thermodynamic resources in the forms of (1) quantum coherence, (2) phase-space features of continuous-variable systems, and (3) temporal patterns in stochastic processes.
