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…
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 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.…
