ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevLett.109.160601 | Abstract: | We study the statistics of the work done, fluctuation relations, and irreversible entropy production in a quantum many-body system subject to the sudden quench of a control parameter. By treating the quench as a thermodynamic transformation we show that the emergence of irreversibility in the nonequilibrium dynamics of closed many-body quantum systems can be accurately characterized. We demonstrate our ideas by considering a transverse quantum Ising model that is taken out of equilibrium by an instantaneous change of the transverse field. © 2012 American Physical Society. | Source Title: | Physical Review Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/96445 | ISSN: | 00319007 | DOI: | 10.1103/PhysRevLett.109.160601 |
