Optimal refrigerator
Armen E. Allahverdyan, Karen Hovhannisyan, Guenter Mahler
We study a refrigerator model which consists of two -level systems interacting via a pulsed external field. Each system couples to its own thermal bath at temperatures and…
Thermodynamics of enhanced heat transfer: a model study
Karen Hovhannisyan, Armen E. Allahverdyan
Situations where a spontaneous process of energy or matter transfer is enhanced by an external device are widespread in nature (human sweating system, enzyme catalysis, facilitated…
Transferring elements of a density matrix
Armen E. Allahverdyan, Karen V. Hovhannisyan
We study restrictions imposed by quantum mechanics on the process of matrix elements transfer. This problem is at the core of quantum measurements and state transfer. Given two sys…
