Boundary-induced geometrical frustration in a square Rydberg-atom lattice
Marco Rigobello, Luka Pavešić, Daniel Jaschke +4
We study geometric defects in square-lattice Rydberg-atom arrays induced by lattice-size parity in the striated density-wave phase. While odd-sized lattices select a single striate…
Disorder-Free Localization and Fragmentation in a Non-Abelian Lattice Gauge Theory
Giovanni Cataldi, Giuseppe Calajó, Pietro Silvi +2
We investigate how isolated quantum many-body systems dynamically equilibrate under non-Abelian gauge-symmetry constraints. By encoding gauge superselection sectors into static $\m…
Quantum Many-Body Scarring in a Non-Abelian Lattice Gauge Theory
Giuseppe Calajò, Giovanni Cataldi, Marco Rigobello +5
Quantum many-body scarring (QMBS) is an intriguing mechanism of weak ergodicity breaking that has recently spurred significant attention. Particularly prominent in Abelian lattice…
Fractional quantum Hall effect in the interacting Hofstadter model via tensor networks
Matthias Gerster, Matteo Rizzi, Pietro Silvi +2
We show via tensor network methods that the Harper-Hofstadter Hamiltonian for hard-core bosons on a square geometry supports a topological phase realizing the fractional qu…
