Old College, Aberystwyth


  • Date:  Tuesday 11th June 2013, 10:00 - 17:00

  • Location:  Aberystwyth University,
          Old College, Modern Languages Room

  • Programm: 
           - 11:30 Guest talk by Guilia Gualdi (Florence):  "Renormalization approach to non-Markovian open quantum system dynamics
                        Abstract: We show that time induces a dynamical renormalization of the system-environment coupling in open quantum system dynamics.
                                                   The renormalization condition, of the interaction being either local, or, alternatively, defined on a finite continuum support, is 
                                                   generally fulfilled for both discrete and continuous environments. As a consequence, we find a generalized Lieb-Robinson bound 
                                                   to hold for local and, surprisingly, also for non-local interaction. This unified picture allows us to devise a controllable approximation
                                                   for arbitrary non-Markovian dynamics with an a priori estimate of the worst case computational cost.
