Analytic results for thermal correlation enhancement after a trap quench
Giorgio Li, Paola Ruggiero, Stefano Scopa
We investigate the nonequilibrium evolution of density correlations in a thermal one-dimensional Bose gas following a trap quench. We focus on the Tonks--Girardeau limit and develo…

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…
