Higher-charge three-dimensional compact lattice Abelian-Higgs models
Claudio Bonati, Andrea Pelissetto, Ettore Vicari
We consider three-dimensional higher-charge multicomponent lattice Abelian-Higgs (AH) models, in which a compact U(1) gauge field is coupled to an N-component complex scalar field…
Lattice Abelian-Higgs model with noncompact gauge fields
Claudio Bonati, Andrea Pelissetto, Ettore Vicari
We consider a noncompact lattice formulation of the three-dimensional electrodynamics with -component complex scalar fields, i.e., the lattice Abelian-Higgs model with noncompac…

Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1
We study the phase diagram and critical behavior of a two-dimensional lattice SO() gauge theory () with two scalar flavors, obtained by partially gauging a maximall…
Dissipative dynamics at first-order quantum transitions
Giovanni Di Meglio, Davide Rossini, Ettore Vicari
We investigate the effects of dissipation on the quantum dynamics of many-body systems at quantum transitions, especially considering those of the first order. This issue is studie…
Asymptotic low-temperature behavior of two-dimensional RP models
Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1
We investigate the low-temperature behavior of two-dimensional (2D) RP models, characterized by a global O() symmetry and a local symmetry. For we…
Dynamics after quenches in one-dimensional quantum Ising-like systems
Davide Rossini, Ettore Vicari
We study the out-of-equilibrium dynamics of one-dimensional quantum Ising-like systems, arising from sudden quenches of the Hamiltonian parameter driving quantum transitions be…

We address the interplay between global and local gauge nonabelian symmetries in lattice gauge theories with multicomponent scalar fields. We consider two-dimensional lattice scala…
Scaling properties of the dynamics at first-order quantum transitions when boundary conditions favor one of the two phases
Andrea Pelissetto, Davide Rossini, Ettore Vicari
We address the out-of-equilibrium dynamics of a many-body system when one of its Hamiltonian parameters is driven across a first-order quantum transition (FOQT). In particular, we…
Dynamic Kibble-Zurek scaling framework for open dissipative many-body systems crossing quantum transitions
Davide Rossini, Ettore Vicari
We study the quantum dynamics of many-body systems, in the presence of dissipation due to the interaction with the environment, under Kibble-Zurek (KZ) protocols in which one Hamil…
Three-dimensional monopole-free CP(N-1) models
Andrea Pelissetto, Ettore Vicari
We investigate the phase diagram, and the nature of the phase transitions, of three-dimensional monopole-free CP(N-1) models, characterized by a global U(N) symmetry and a U(1) gau…

We investigate the phase diagram and finite-temperature transitions of three-dimensional scalar SO(Nc) gauge theories with Nf scalar flavors. These models are constructed starting…
Measurement-induced dynamics of many-body systems at quantum criticality
Davide Rossini, Ettore Vicari
We consider a dynamic protocol for quantum many-body systems, which enables to study the interplay between unitary Hamiltonian driving and random local projective measurements. Whi…
Universal low-temperature behavior of two-dimensional lattice scalar chromodynamics
