DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QMFNoT/51/">
 Noncommuting conserved charges in quantum thermodynamics and beyond</a>\nb
 y Aleksander A. Lasek (UMD) as part of QM Foundations & Nature of Time sem
 inar\n\n\nAbstract\nQuantum simulators have recently enabled experimental 
 observations of the internal thermalization of quantum many-body systems. 
 Often\, the global energy and particle number are conserved and the system
  is prepared with a well-defined particle number—in a microcanonical sub
 space. However\, quantum evolution can also conserve quantities\, or charg
 es\, that fail to commute with each other. Noncommuting charges have recen
 tly emerged as a subfield at the intersection of quantum thermodynamics an
 d quantum information.  I will give a brief introduction to the field of q
 uantum noncommuting thermodynamics\, as well as present our original resul
 ts. Until recently\, this subfield has remained theoretical. We initiate t
 he experimental testing of its predictions\, with a trapped-ion simulator.
   We find that small subsystems equilibrate to near a recently predicted n
 on-Abelian thermal state. This work bridges quantum many-body simulators t
 o the quantum thermodynamics of noncommuting charges\, the predictions of 
 which can now be tested\n
