SUMMARY:Many body localization: a new frontier for quantum statistical
physics\, R. G. Herb Condensed Matter Seminar\, Rahul Nandkishore\, P
rinceton University
DESCRIPTION:"The existing theory of quantum statistical mechanics desc
ribes open systems in contact with large reservoirs. However\, experim
ental advances in the construction and control of isolated quantum sys
tems have highlighted the need for an analogous theory of isolated sys
tems. It has been realized that isolated quantum systems can support b
ehavior which has no analog in open quantum systems. A prominent examp
le is the phenomenon of many body localization.
\n
\nMany bo
dy localization occurs in isolated quantum systems\, usually with stro
ng disorder\, and is marked by absence of dissipation\, absence of the
rmal equilibration\, a strictly zero DC conductivity (even at energy d
ensities corresponding to high temperatures)\, and a memory of the ini
tial conditions that survives in local observables for arbitrarily lon
g times. Recently\, my co-workers and I have demonstrated that many bo
dy localization also opens the door to new states of matter which cann
ot exist in thermal equilibrium\, such as topological order at finite
energy density\, or broken symmetry states below the equilibrium lower
critical dimension. In this talk\, I review the essential features of
the many body localization phenomenon\, present our recent work on lo
calization protected order\, and provide a survey of open problems. I
also present my ongoing work seeking to make contact between the theor
y and experiments\, and discuss potential technological applications o
f these ideas.“
