The smallest possible thermal machines and the foundations of thermodynamics

by Sandu Popescu (University of Bristol, UK)

Tuesday, 30 May 2017 from to (Europe/Bucharest)
at National Physics Library
Description In my talk I raise the question on the fundamental limits to the size of thermal machines – refrigerators, heat pumps and work producing engines and I will present the smallest possible ones. I will then discuss the issue of a possible complementarity between size and efficiency and show that even the smallest machines could be maximally efficient and I will also present a new point of view over what is work and what do thermal machines actually do.
Finally I will present a completely new approach to the foundations of thermodynamics that follows from these results.
