Engineering of non-Hermitian interactions in digital qudit quantum simulators
Matteo M. Wauters, Paolo Boschetto, Edoardo Ballini +2
Non-Hermitian Hamiltonians are a fascinating class of many-body models that describe the effective dynamics of quantum systems interacting with the environment through particle, en…
Theory of the correlated quantum Zeno effect in a monitored qubit dimer
Severino Zeni, Gobinda Chakraborty, Alessandro Romito +1
We theoretically investigate the stochastic dynamics of two qubits subject to one- and two-site correlated continuous weak measurements. When measurements dominate over the local u…
Quantum jump correlations in long-range dissipative spin systems via cluster and cumulant expansions
Giulia Salatino, Anna Delmonte, Zejian Li +2
We characterize nonequilibrium phases in long-range dissipative spin systems through the statistical properties of quantum jump trajectories. While the average dynamics governed by…
Dissipative quantum North-East-Center model: steady-state phase diagram, universality and nonergodic dynamics
Pietro Brighi, Alberto Biella
In this work we study the dissipative quantum North-East-Center (NEC) model: a two-dimensional spin-1/2 lattice subject to chiral, kinetically constrained dissipation and coherent…
Symmetry-protection Zeno phase transition in monitored lattice gauge theories
Matteo M. Wauters, Edoardo Ballini, Alberto Biella +1
Quantum measurements profoundly influence system dynamics. They lead to complex nonequilibrium phenomena like the quantum Zeno effect, and they can be used for mitigating errors in…
Open quantum systems -- A brief introduction
Fabrizio Minganti, Alberto Biella
This text is a short introduction to the physics of driven-dissipative many-body systems, focusing on a few selected topics. Beyond its more ``historical'' interest in the study of…
