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…
Berezinskii-Kosterlitz-Thouless transitions in two-dimensional lattice SO() gauge theories with two scalar flavors
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…
Asymptotic low-temperature critical behavior of two-dimensional multiflavor lattice SO(Nc) gauge theories
Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1
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…
