Information transport and transport-induced entanglement in open fermion chains
Andrea Nava, Claudia Artiaco, Yuval Gefen +4
Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin…
Higher-Dimensional Information Lattice: Quantum State Characterization through Inclusion-Exclusion Local Information
Ian Matthias Flór, Claudia Artiaco, Thomas Klein Kvorning +1
We generalize the information lattice, originally defined for one-dimensional open-boundary chains, to characterize quantum many-body states in higher-dimensional geometries. In on…
Witnessing Short- and Long-Range Nonstabilizerness via the Information Lattice
Yuliya Bilinskaya, Miguel F. Martínez, Soumi Ghosh +3
We study nonstabilizerness on the information lattice, and demonstrate that noninteger local information directly indicates nonstabilizerness. For states with a clear separation of…
Out-of-Equilibrium Dynamics in a U(1) Lattice Gauge Theory via Local Information Flows: Scattering and String Breaking
Claudia Artiaco, João Barata, Enrique Rico
We introduce local information flows as a diagnostic tool for characterizing out-of-equilibrium quantum dynamics in lattice gauge theories. We employ the information lattice framew…
Local Information Flow in Quantum Quench Dynamics
Nicolas P. Bauer, Björn Trauzettel, Thomas Klein Kvorning +2
We investigate the out-of-equilibrium dynamics of quantum information in one-dimensional systems undergoing a quantum quench using a local perspective based on the information latt…
Numerical Study of Disordered Noninteracting Chains Coupled to a Local Lindblad Bath
Viktor Berger, Andrea Nava, Jens H. Bardarson +1
Disorder can prevent many-body quantum systems from reaching thermal equilibrium, leading to a many-body localized phase. Recent works suggest that nonperturbative effects caused b…
