Exact thermalization dynamics in the "Rule 54" Quantum Cellular Automaton
Katja Klobas, Bruno Bertini, Lorenzo Piroli
We study the out-of-equilibrium dynamics of the quantum cellular automaton known as "Rule 54". For a class of low-entangled initial states, we provide an analytic description of th…
Prethermalisation and Thermalisation in the Entanglement Dynamics
Bruno Bertini, Pasquale Calabrese
We investigate the crossover of the entanglement entropy towards its thermal value in nearly integrable systems. We employ equation of motion techniques to study the entanglement d…
Correlations in Perturbed Dual-Unitary Circuits: Efficient Path-Integral Formula
Pavel Kos, Bruno Bertini, Tomaž Prosen
Interacting many-body systems with explicitly accessible spatio-temporal correlation functions are extremely rare, especially in the absence of integrability. Recently, we identifi…
Scrambling in Random Unitary Circuits: Exact Results
Bruno Bertini, Lorenzo Piroli
We study the scrambling of quantum information in local random unitary circuits by focusing on the tripartite information proposed by Hosur et al. We provide exact results for the…
Exact dynamics in dual-unitary quantum circuits
Lorenzo Piroli, Bruno Bertini, J. Ignacio Cirac +1
We consider the class of dual-unitary quantum circuits in dimensions and introduce a notion of ``solvable'' matrix product states (MPSs), defined by a specific condition whic…
Operator Entanglement in Local Quantum Circuits II: Solitons in Chains of Qubits
Bruno Bertini, Pavel Kos, Tomaz Prosen
We provide exact results for the dynamics of local-operator entanglement in quantum circuits with two-dimensional wires featuring ultralocal solitons, i.e. single-site operators wh…
