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…
Microscopic origin of the quantum Mpemba effect in integrable systems
Colin Rylands, Katja Klobas, Filiberto Ares +3
The highly complicated nature of far from equilibrium systems can lead to a complete breakdown of the physical intuition developed in equilibrium. A famous example of this is the M…
Quench dynamics in lattices above one dimension: the free fermionic case
Molly Gibbins, Arash Jafarizadeh, Adam Gammon-Smith +1
We begin a systematic investigation of quench dynamics in higher-dimensional lattice systems considering the case of non-interacting fermions with conserved particle number. We pre…
Dynamics of charge fluctuations from asymmetric initial states
Bruno Bertini, Katja Klobas, Mario Collura +2
Conserved-charge densities are very special observables in quantum many-body systems as, by construction, they encode information about the dynamics. Therefore, their evolution is…
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…
Exact quench dynamics of the Floquet quantum East model at the deterministic point
Bruno Bertini, Cecilia De Fazio, Juan P. Garrahan +1
We study the nonequilibrium dynamics of the Floquet quantum East model (a Trotterized version of the kinetically constrained quantum East spin chain) at its "deterministic point",…
