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.…
Dissipatively dressed quasiparticles in boundary driven integrable spin chains
Vladislav Popkov, Xin Zhang, Carlo Presilla +1
The nonequilibrium steady state (NESS) of integrable spin chains experiencing strong boundary dissipation is accounted by introducing quasiparticles with a renormalized -- dissipat…
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…
Bethe-ansatz diagonalization of steady state of boundary driven integrable spin chains
Vladislav Popkov, Xin Zhang, Carlo Presilla +1
We find that the density operator of non-equilibrium steady state (NESS) of XXZ spin chain with strong ``sink and source" boundary dissipation, can be described in terms of quasipa…
Perturbative criteria for the ergodicity of interacting dissipative quantum lattice systems
Lorenzo Bertini, Alberto De Sole, Gustavo Posta +1
We introduce a class of quantum Markov semigroups describing the evolution of interacting quantum lattice systems, specified either as generic qudits or as fermions. The correspond…
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…
