Rigorous existence and location of quantum phase transitions in lattice Hamiltonian systems
Massimo Ostilli, Carlo Presilla
We extend the analysis of the class of quantum phase transitions (QPTs) that can be interpreted as condensations in state space, first introduced in [M. Ostilli and C. Presilla, J.…
Manifolds of exceptional points and effective Zeno limit of an open two-qubit system
Vladislav Popkov, Carlo Presilla, Mario Salerno
We analytically investigate the Liouvillian exceptional point manifolds (LEPMs) of a two-qubit open system, where one qubit is coupled to a dissipative polarization bath. Exploitin…
Finite temperature quantum condensations in the space of states: General Proof
Massimo Ostilli, Carlo Presilla
We formalize and prove the extension to finite temperature of a class of quantum phase transitions, acting as condensations in the space of states, recently introduced and discusse…
Finite temperature quantum condensations in the space of states: a new perspective for quantum annealing
Massimo Ostilli, Carlo Presilla
In nature, everything occurs at finite temperature and quantum phase transitions (QPTs) cannot be an exception. Nevertheless, they are still mainly discussed and formulated at zero…
Full spectrum of the Liouvillian of open dissipative quantum systems in the Zeno limit
Vladislav Popkov, Carlo Presilla
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 rela…
Dissipative generation of pure steady states and a gambler's ruin problem
Vladislav Popkov, Simon Essink, Corinna Kollath +1
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 regi…
