Liouvillian Exceptional Points in Quantum Brickwork Circuits
Vladislav Popkov, Mario Salerno
We demonstrate that Liouvillian exceptional points (LEPs), previously explored only in continuous Lindbladian dynamics, also emerge in discrete brickwork completely positive trace-…
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…
Manipulating energy and spin currents in nonequilibrium systems of interacting qubits
Vladislav Popkov, Roberto Livi
We consider generic interacting chain of qubits, which are coupled at the edges to baths of fixed polarizations. We can determine the nonequilibrium steady states, described by the…
Scaling of the von Neumann entropy across a finite temperature phase transition
Vladislav Popkov, Mario Salerno
The spectrum of the reduced density matrix and the temperature dependence of the von Neumann entropy (VNE) are analytically obtained for a system of hard core bosons on a complete…
