Dominance and equivalence for states on -algebras: Quasi-Invariant states

Ameur Dhahri, Francesco Fidaleo, Chul Ki Ko +1

We study the noncommutative generalization of measure-theoretic dominance and equivalence of states on -algebras to explore quasi-invariance under group actions. For a dominat…

Quasi-stationary normal states for quantum Markov semigroups

Ameur Dhahri, Franco Fagnola, Federico Girotti +1

We introduce the notion of Quasi-Stationary State (QSS) in the context of quantum Markov semigroups that generalizes the one of quasi-stationary distribution in the case of classic…

Quasi-invariant states with uniformly bounded cocycles

Ameur Dhahri, Eric Ricard

We investigate the notion of quasi-invariant states introduced in [2, 3] from an analytic viewpoint.We give the structures of quasi-invariant states with uniformly bounded cocycles…

Environment induced entanglement in Gaussian open quantum systems

A. Dhahri, F. Fagnola, D. Poletti +1

We show that a bipartite Gaussian quantum system interacting with an external Gaussian environment may possess a unique Gaussian entangled stationary state and that any initial sta…

Martingales associated with strongly quasi-invariant states

Ameur Dhahri, Chul Ki Ko, Hyun Jae Yoo

We discuss the martingales in relevance with -strongly quasi-invariant states on a -algebra , where is a separable locally compact group of -automorphism…

Group of automorphisms for strongly quasi invariant states

Ameur Dhahri, Chul Ki Ko, Hyun Jae Yoo

For a -automorphism group on a - or von Neumann algebra, we study the -quasi invariant states and their properties. The -quasi invariance or -strongly quasi in…
