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. <br>
\n <br>
\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.“<br>
