THE SEMINAR

THEORY OF DUALITY

DEPARTMENT OF MATHEMATICAL METHODS IN PHYSICS



On the 17th of March 2016, at 10:15 a.m.

Stanisław L. Woronowicz (KMMF WFUW)

will give a talk on

"Passive states of quantum systems"

Abstract
In the algebraic quantum theory we know a few properties characterising equilibrium states. These are KMS-condition, stability and passivity. Passivity is the property suggested by second law of thermodynamics. By definition a quantum system is in a passive state if it is unable to perform a work in any cyclic adiabatic process. I shall give mathematical formulation of this property and discuss its implications. In particular the relation between passivity and KMS-condition will be discussed. As an application the famous Carnot formula for the efficiency of heat engines will be derived. (Based on a joint paper with W. Pusz)

The seminar takes place on Thursdays from 10:15 a.m. to 12:00 in the room 2.23 of the main building of the Faculty of Physics (the 2nd floor), Pasteur Str. 5, Warszawa.
