Martedi 17 maggio 2016 alle ore 15.00, presso l'aula B del plesso di via Archirafi 36, il Dr. Kimmo Luoma della Technical University di Dresda terrà un seminario dal titolo:

"Collision model for non-Markovian quantum dynamics"

Abstract:

We study the applicability of collisional models for non-Markovian dynamics of open quantum
systems. By allowing interactions between the separate environmental degrees of freedom in between
collisions we are able to construct a collision model that allows to study quantum memory effects
in open system dynamics. We also discuss the possibility to embed non-Markovian collision model
dynamics into Markovian collision model dynamics in an extended state space. As a concrete
example we show how using the proposed class of collision models we can discretely model non-
Markovian amplitude damping of a qubit. In the time-continuous limit, we obtain the well-known
results for spontaneous decay of a two level system in to a structured zero-temperature reservoir.
