Joint ICTP/SISSA Statistical Physics seminar: "Entanglement and particle identity"
SISSA, Santorio Building
Room 005, 1st floor
Via Bonomea 265
ABSTRACT
Entanglement of quantum states generically emerges via a partial observation. Such observations are usually encoded by the operation of a partial trace over one of the components.of the system. Nevertheless it is well-known that partial trace is not suitable to deal with general systems such as those involving identical particles. Recently (Phys. Rev. Lett. 110, 080503 (2013)) we have proposed a procedure to address this problem of identical particles in a proper manner. The procedure is based on the properties of the algebra of observables of the system and the GNS (Gelfand-Naimark-Siegel) construction of representations of such algebra. In the present seminar, we present our proposed approach to this problem and discuss some of its applications and consequences. Further references are (arXiv:1212.1239, arXiv:1301.1300, arXiv:1302.4924).
