When the center matters: color screening and gluelumps in dihedral lattice gauge theories
Pavel P. Popov, Edoardo Ballini, Alberto Bottarelli +4
Confinement is one of the hallmarks of quantum chromodynamics (QCD), but its first-principles characterization remains elusive. We show that discrete non-Abelian lattice gauge theo…
Optimal local basis truncation of lattice quantum many-body systems
Peter Majcen, Giovanni Cataldi, Pietro Silvi +1
We show how to optimally reduce the local Hilbert basis of lattice quantum many-body (QMB) Hamiltonians. The basis truncation exploits the most relevant eigenvalues of the estimate…
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…
Many-body quantum dimerization in 2D atomic arrays
Giuseppe Calajò, Matija Tečer, Simone Montangero +2
We consider a 2D atomic array coupled to different photonic environments, focusing on the half-filled excitation subspace, where strong photon interactions can give rise to complex…
Entanglement transitions in a boundary-driven open quantum many-body system
Darvin Wanisch, Nora Reinić, Daniel Jaschke +2
We introduce a numerical framework for integrating Markovian dynamics on tree tensor operator (TTO) ansatz states. This framework enables the simulation of both transient and stead…
