Calendar of Physics Talks Vienna

The smallest possible thermal machines and the foundations of thermodynamics
Speaker:Prof. Sandu Popescu (University of Bristol, UK)
Abstract: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 also discuss the issue of a possible complementarity between size and efficiency and show that even the smallest machines could be maximally efficient. Finally I will present a new point of view over what is work and what do thermal machines actually do.
