IPB Colloquium by Pasquale Calabrese

The IPB colloquium will be held on Friday, 29 December 2017 at 12:00 in the “Zvonko Marić” lecture hall of the Institute of Physics Belgrade. The talk entitled

"Entanglement and thermodynamics in non-equilibrium isolated quantum systems"

will be given by the ERC grant recipient, Prof. Pasquale Calabrese (SISSA - International School for Advanced Studies, Trieste, Italy).

Abstract of the talk:

Entanglement and entropy are key concepts standing at the foundations of quantum and statistical mechanics. In the last decade the study of the non-equilibrium dynamics of isolated quantum systems revealed that these two concepts are intricately intertwined. Although the unitary time evolution ensuing from a pure initial state maintains the system globally at zero entropy, at long time after the quench local properties are captured by an appropriate statistical ensemble with non-zero thermodynamic entropy, which can be interpreted as the entanglement accumulated during the dynamics. Therefore, understanding the post-quench entanglement evolution unveils how thermodynamics emerges in isolated quantum systems.
