Statistics of non-conserved observables in Lindblad master equations
G. Modanese
We study the dynamics of observables that are conserved under the Hamiltonian evolution of a closed quantum system, but cease to be conserved when the system is coupled to a Markov…

Excited states of coherent harmonic qubits with long-range photon coupling and dissipation
L. Gamberale, G. Modanese
It is known that ensembles of interacting oscillators or qubits can exhibit the phenomenon of quantum synchronization. In this work we consider a set of identical two-state sys…

Generalized local charge conservation in many-body quantum mechanics
F. Minotti, G. Modanese
In the framework of the quantum theory of many-particle systems, we study the compatibility of approximated Non-Equilibrium Green Functions (NEGFs) and of approximated solutions of…
