Boundary time crystals
F. Iemini, A. Russomanno, J. Keeling +3
In this work we introduce {\it boundary time-crystals}. Here {\it continuous} time-translation symmetry breaking occurs only in a macroscopic fraction of a many-body quantum system…
Direct comparison of quantum and simulated annealing on a fully-connected Ising ferromagnet
Matteo M. Wauters, Rosario Fazio, Hidetoshi Nishimori +1
We compare the performance of quantum annealing (QA, through Schrödinger dynamics) and simulated annealing (SA, through a classical master equation) on the -spin infinite range…
Dissipation in adiabatic quantum computers: Lessons from an exactly solvable model
Maximilian Keck, Simone Montangero, Giuseppe E. Santoro +2
We introduce and study the adiabatic dynamics of free-fermion models subject to a local Lindblad bath and in the presence of a time-dependent Hamiltonian. The merit of these models…
Stabilizing strongly correlated photon fluids with non-Markovian reservoirs
José Lebreuilly, Alberto Biella, Florent Storme +4
We introduce a novel frequency-dependent incoherent pump scheme with a square-shaped spectrum as a way to study strongly correlated photons in arrays of coupled nonlinear resonator…
Density-of-states of many-body quantum systems from tensor networks
Fabian Schrodi, Pietro Silvi, Ferdinand Tschirsich +2
We present a technique to compute the microcanonical thermodynamical properties of a manybody quantum system using tensor networks. The Density Of States (DOS), and more general sp…
Multipartite entanglement after a quantum quench
Silvia Pappalardi, Angelo Russomanno, Alessandro Silva +1
We study the multipartite entanglement of a quantum many-body system undergoing a quantum quench. We quantify multipartite entanglement through the quantum Fisher information (QFI)…
