Observation of far-from-equilibrium scaling in the transient dynamics of 2D quantum magnets
Fabio Bensch, Umberto Borla, Federico Balducci +7
The transient regime of far-from-equilibrium quantum many-body dynamics lacks the established organizing principles that universality and scaling provide in equilibrium. It is leas…
Odd Toric Code in a tilted field: Higgs-confinement multicriticality, spontaneous self-duality symmetry breaking, and valence bond solids
Umberto Borla, Ayush De, Snir Gazit
We investigate the quantum phase diagram of an ``odd'' variant of the two-dimensional Ising Fradkin--Shenker model, characterized by a uniform background of static and char…
Spontaneously Broken Non-Invertible Symmetries in Transverse-Field Ising Qudit Chains
Kristian Tyn Kai Chung, Umberto Borla, Andriy H. Nevidomskyy +1
Recent developments have revealed that symmetries need not form a group, but instead can be non-invertible. Here we use analytical arguments and numerical evidence to illuminate ho…
Projected Entangled Pair States for Lattice Gauge Theories with Dynamical Fermions
Ariel Kelman, Umberto Borla, Patrick Emonts +1
Lattice gauge theory is an important framework for studying gauge theories that arise in the Standard Model and condensed matter physics. Yet many systems (or regimes of those syst…
Finite-Temperature Dynamical Phase Diagram of the D Quantum Ising Model
Lucas Katschke, Roland C. Farrell, Umberto Borla +2
Mapping finite-temperature dynamical phase diagrams of quantum many-body models is a necessary step towards establishing a framework of far-from-equilibrium quantum many-body unive…
Matter-induced plaquette terms in a lattice gauge theory
Matjaž KebriÄ, Fabian Döschl, Umberto Borla +4
Lattice gauge theories (LGTs) provide a powerful framework for studying confinement, topological order, and exotic quantum matter. In particular, the paradigmatic phenomenon of con…
