Universality in the tripartite information after global quenches

V Marić, M Fagotti - Physical Review B, 2023 - APS
We consider macroscopically large 3-partitions (A, B, C) of connected subsystems A∪ B∪ C
in infinite quantum spin chains and study the Rényi-α tripartite information I 3 (α)(A, B, C). At …

Entanglement entropy of two disjoint intervals and spin structures in interacting chains in and out of equilibrium

V Marić, S Bocini, M Fagotti - Journal of High Energy Physics, 2024 - Springer
A bstract We take the paradigm of interacting spin chains, the Heisenberg spin-\(\frac {1}{2}\)
XXZ model, as a reference system and consider interacting models that are related to it by …
