Hi Everyone,
This seminar might be of interest:
Please join us at *12:00pm on Tuesday, May 20 * for a Condensed Matter
Physics Seminar with Claudio Chamon from Boston University.
The details of Claudio's presentation are listed below
*Title: * *"*Emergent irreversibility and entanglement spectrum statistics
*"*
*Abstract:* We study the problem of irreversibility when the dynamical
evolution of a many-body system is described by a stochastic quantum
circuit. Such evolution is more general than a Hamitonian one, and since
energy levels are not well defined, the well-established connection between
the statistical fluctuations of the energy spectrum and irreversibility
cannot be made. We show that the entanglement spectrum provides a more
general connection. Irreversibility is marked by a failure of a
disentangling algorithm and is preceded by the appearance of Wigner-Dyson
statistical fluctuations in the entanglement spectrum. This analysis can be
done at the wave function level and offers an alternative route to study
quantum chaos and quantum integrability.
*Date*: Tuesday May 20, 2014
Time: 12:00pm
Location: Duboc Seminar Room (4-331)
