Out-of-equilibrium finite-size scaling in generalized Kibble-Zurek protocols crossing quantum phase transitions in the presence of symmetry-breaking perturbations

Francesca De Franco, Ettore Vicari

We study the effects of symmetry-breaking perturbations in the out-of-equilibrium quantum dynamics of many-body systems slowly driven across a continuous quantum transition (CQT) b…

Quantum critical behaviors and decoherence of weakly coupled quantum Ising models within an isolated global system

Alessio Franchi, Andrea Pelissetto, Ettore Vicari

We discuss the quantum dynamics of an isolated composite system consisting of weakly interacting many-body subsystems. We focus on one of the subsystems, S, and study the dependenc…

Entanglement negativity in a fermionic chain with dissipative defects: Exact results

Fabio Caceffo, Vincenzo Alba

We investigate the dynamics of the fermionic logarithmic negativity in a free-fermion chain with a localized loss, which acts as a dissipative impurity. The chain is initially prep…

Logarithmic entanglement scaling in dissipative free-fermion systems

Antonio D'Abbruzzo, Vincenzo Alba, Davide Rossini

We study the quantum information spreading in one-dimensional free-fermion systems in the presence of localized thermal baths. We employ a nonlocal Lindblad master equation to desc…

Out-of-equilibrium dynamics arising from slow round-trip variations of Hamiltonian parameters across quantum and classical critical points

Francesco Tarantelli, Ettore Vicari

We address the out-of-equilibrium dynamics of many-body systems subject to slow time-dependent round-trip protocols across quantum and classical (thermal) phase transitions. We con…

Entangled multiplets and unusual spreading of quantum correlations in a continuously monitored tight-binding chain

Federico Carollo, Vincenzo Alba

We analyze the dynamics of entanglement in a paradigmatic noninteracting system subject to continuous monitoring of the local excitation densities. Recently, it was conjectured tha…

Decoherence and energy flow in the sunburst quantum Ising model

Alessio Franchi, Davide Rossini, Ettore Vicari

We study the post-quench unitary dynamics of a quantum sunburst spin model, composed of a transverse-field quantum Ising ring which is suddenly coupled to a set of independent exte…

Scalar gauge-Higgs models with discrete Abelian symmetry groups

Claudio Bonati, Andrea Pelissetto, Ettore Vicari

We investigate the phase diagram and the nature of the phase transitions of three-dimensional lattice gauge-Higgs models obtained by gauging the Z_N subgroup of the global Z_q inva…

Growth of Rényi Entropies in Interacting Integrable Models and the Breakdown of the Quasiparticle Picture

Bruno Bertini, Katja Klobas, Vincenzo Alba +2

Rényi entropies are conceptually valuable and experimentally relevant generalisations of the celebrated von Neumann entanglement entropy. After a quantum quench in a clean quantum…

Three-dimensional monopole-free CP models: Behavior in the presence of a quartic potential

Claudio Bonati, Andrea Pelissetto, Ettore Vicari

We investigate the phase diagram and the nature of the phase transitions in a three-dimensional model characterized by a global SU() symmetry, a local U(1) symmetry, and the abs…

Quantum many-body spin rings coupled to ancillary spins: The sunburst quantum Ising model

Alessio Franchi, Davide Rossini, Ettore Vicari

We study the ground-state properties of a quantum "sunburst model", composed of a quantum Ising spin-ring in a transverse field, symmetrically coupled to a set of ancillary isolate…

Critical behaviors of lattice U(1) gauge models and three-dimensional Abelian-Higgs gauge field theory

Claudio Bonati, Andrea Pelissetto, Ettore Vicari

We investigate under which conditions the three-dimensional (3D) multicomponent Abelian-Higgs (AH) field theory (scalar electrodynamics) is the continuum limit of statistical latti…

Critical crossover phenomena driven by symmetry-breaking defects at quantum transitions

Alessio Franchi, Davide Rossini, Ettore Vicari

We study the effects of symmetry-breaking defects at continuous quantum transitions (CQTs), which may arise from localized external fields coupled to the order-parameter operator.…
