Entanglement of Disjoint Intervals in Dual-Unitary Circuits: Exact Results
Alessandro Foligno, Bruno Bertini
The growth of the entanglement between two disjoint intervals and its complement after a quantum quench is regarded as a dynamical chaos indicator. Namely, it is expected to show q…

Non-equilibrium dynamics of charged dual-unitary circuits
Alessandro Foligno, Pasquale Calabrese, Bruno Bertini
The interplay between symmetries and entanglement in out-of-equilibrium quantum systems is currently at the centre of an intense multidisciplinary research effort. Here we introduc…

Quantum information spreading in generalised dual-unitary circuits
Alessandro Foligno, Pavel Kos, Bruno Bertini
We study the spreading of quantum information in a recently introduced family of brickwork quantum circuits that generalises the dual-unitary class. These circuits are unitary in t…
