Full spectrum of the Liouvillian of open dissipative quantum systems in the Zeno limit
Vladislav Popkov, Carlo Presilla
Izvirni znanstveni članek
Oznake: kvantna mehanika;odprti kvantni sistemi;nelinearna dinamika;quantum mechanics;open quantum systems;nonlinear dynamics;
We consider an open quantum system with dissipation, described by a Lindblad Master equation (LME). For dissipation locally acting and sufficiently strong, a separation of the relaxation timescales occurs, which, in terms of the eigenvalues of the Liouvillian, implies a grouping of the latter in dis ...

We consider an open quantum system, with dissipation applied only to a part of its degrees of freedom, evolving via a quantum Markov dynamics. We demonstrate that, in the Zeno regime of large dissipation, the relaxation of the quantum system towards a pure quantum state is linked to the evolution of ...
