Second Qymru Meeting

11th June 2013, 11:30 - 17:00

Aberystwyth University, Old College, Modern Languages Room

11:30 Guest talk by Guilia Gualdi (Florence): "Renormalization approach to non-Markovian open quantum system dynamics"

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.

12:30 Lunch
