Field-Space Entanglement Dynamics Between Tunnel-Coupled Luttinger Liquids
Léonce Dupays, Taufiq Murtadho, Bi Hong Tiang +2
Entanglement dynamics depend not only on how a quantum system is partitioned, but critically on how interactions across that partition are structured. For a spatial bipartition of…
Charged moments and symmetry-resolved entanglement from Ballistic Fluctuation Theory
Giorgio Li, Léonce Dupays, Paola Ruggiero
The charged moments of a reduced density matrix provide a natural starting point for deriving symmetry-resolved Rényi and entanglement entropies, which quantify how entanglement is…
A Hydrodynamic Theory for Non-Equilibrium Full Counting Statistics in One-Dimensional Quantum Systems
David X. Horvath, Benjamin Doyon, Paola Ruggiero
We study the dynamics of charge fluctuations after homogeneous quantum quenches in one-dimensional systems with ballistic transport. For short but macroscopic times where the non-t…
Full counting statistics after quantum quenches as hydrodynamic fluctuations
David X. Horvath, Benjamin Doyon, Paola Ruggiero
The statistics of fluctuations on large regions of space encodes universal properties of many-body systems. At equilibrium, it is described by thermodynamics. However, away from eq…
