TODAY - CME Seminar with Rajdeep Sensarma in the Smith Seminar room at 11:30am.

[Patterson, Robin L.]

Please join us for a Condensed Matter Seminar featuring Rajdeep Sensarma of Tata Institute of Fundamental Research, Mumbai .
His seminar on "Memories of Initial States in Dynamics of Many Body Localized Systems"  will be held in the Smith Seminar Room today, March 21 from 11:30am- 1:00pm.

Memories of Initial States in Dynamics of Many Body Localized Systems
Rajdeep Sensarma
Tata Institute of Fundamental Research, Mumbai

Strongly disordered interacting systems cannot act as a thermal bath for a subsystem, a phenomenon called many body localization.
At long times, the system still remembers the initial state it started from, leading to a breakdown of applicability of equilibrium statistical mechanics.  This memory of initial states has been measured in recent experiments in ultracold atomic systems.  We develop a new field theoretic description which can describe non-equilibrium dynamics of many body systems starting from arbitrary initial conditions.
We use this to derive exact answers for the experimental observables in the non-interacting system. In the interacting systems,
we show that the bath generated during the dynamics remembers the initial condition, leading to a finite memory in these systems.
