Hi all,
please join us tomorrow at 4 pm in the Alice Room for a quantum
information seminar by Isaac Kim.
Title: *Application of conditional independence to gapped quantum
many-body systems*
Speaker: *Isaac Kim* (Caltech)
Abstract:
It is widely known in the quantum information community that the states
that satisfy strong subadditivity of entropy with equality have the form
of quantum Markov chain. Based on a recent strengthening of strong
subadditivity of entropy, I will describe how such structure can be
exploited in the studies of gapped quantum many-body system. In
particular, I will describe a diagrammatic trick to i) give a
quantitative statement about the locality of entanglement spectrum ii)
perturbatively bound changes of topological entanglement entropy under
generic perturbation.
Date: Wednesday, Dec 12, 2012 - 4:00 pm
Location: Alice Room (301)
Best,
Markus
