Title: Quantum Thermodynamics and Quantum Heat Engines

Date & Time: Thursday 14th September, 2017 at 4.00 PM

Venue: SSCU AUDITORIUM

Abstract:

The concept of a ‘quantum thermodynamical cycle’ that emerges as a quantum mechanical analogy of the classical thermodynamical cycle has been an attractive field of theoretical research for last fifty years. At the nanoscale,quantum properties become important and have thus to be fully taken into account. Like classical thermodynamics, a quantum heat engines (QHEs) generates useful mechanical work from heat but the main feature here is that it uses quantum matter as the working substance. QHEs consist of several basic thermodynamics processes. I will begin my talk by explaining all the thermodynamics processes in quantum thermodynamics and then I will discuss classical Carnot engine andOtto engine and quantum analogues of them. In the next part, I will talk about how quantum heat engine offers a practicalalternative to Szilard’ s engine to physically realize maxwell’s demon. The last topic will be the experimental scheme torealize a nanoheat engine with a single ion.
