Statistical mechanics of entanglement — •Jarek Korbicz, Florian Hulpke, and Maciej Lewenstein — Institut für Theoretische Physik, Universität Hannover, Appelstr. 2, 30167 Hannover, Germany

We apply the methods of statistical mechanics to the study of entanglement. We consider the space of decompositions of a given density matrix. In this space we introduce a polynomial cost-function, minimized by decompositions composed entirely of projectors onto product vectors. We next assume that the number of terms in each decomposition is large and define an analog of a canonical partition function. We study it analytically and numerically for a family of Werner states of two qubits.
