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…
