Complete positivity and dissipative factorized dynamics: some comments
F. Benatti, R. Floreanini, M. Piani +1
After reviewing the main properties of time-evolutions of open quantum systems, some considerations about the positivity of factorized Markovian dynamics for bipartite systems are…
Neutral kaons in random media
F. Benatti, R. Floreanini, R. Romano
The generalized dynamics describing the propagation of neutral kaons in randomly fluctuating media is derived and analyzed. It takes into account possible matter-induced effects le…
Environment Induced Entanglement in Markovian Dissipative Dynamics
F. Benatti, R. Floreanini, M. Piani
We show that two, non interacting 2-level systems, immersed in a common bath, can become mutually entangled when evolving according to a Markovian, completely positive reduced dyna…
About non-positive evolutions in open system dynamics
F. Benatti, R. Floreanini, M. Piani
The long-time evolution of a system in interaction with an external environment is usually described by a family of linear maps g_t, generated by master equations of Block-Redfield…
