Color-flavor reflection in the continuum limit of two-dimensional lattice gauge theories with scalar fields
Claudio Bonati, Alessio Franchi
We address the interplay between local and global symmetries in determining the continuum limit of two-dimensional lattice scalar theories characterized by gauge symmetry…
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.…
Continuum limit of two-dimensional multiflavor scalar gauge theories
Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1
We address the interplay between local and global symmetries by analyzing the continuum limit of two-dimensional multicomponent scalar lattice gauge theories, endowed by non-Abelia…
Three-dimensional lattice SU() gauge theories with multiflavor scalar fields in the adjoint representation
Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1
We consider three-dimensional lattice SU() gauge theories with multiflavor () scalar fields in the adjoint representation. We investigate their phase diagram, identify…
Two-dimensional lattice SU() gauge theories with multiflavor adjoint scalar fields
Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1
We consider two-dimensional lattice SU() gauge theories with real scalar fields transforming in the adjoint representation of the gauge group and with a global O()…
