On the integrability structure of the deformed rule-54 reversible cellular automaton
Chiara Paletta, Tomaž Prosen
We study quantum and stochastic deformations of the rule-54 reversible cellular automaton (RCA54) on a 1+1-dimensional spatiotemporal lattice, focusing on their integrability struc…
Open-boundary integrable quantum circuits with different geometries
Miguel GarcÃa Fernández, Chiara Paletta, Ana L. Retore
We present a complete classification of integrable Yang-Baxter quantum circuits with open boundary conditions and arbitrary circuit geometries. Starting from the standard transfer-…
Integrability and charge transport in asymmetric quantum-circuit geometries
Chiara Paletta, Urban Duh, Balázs Pozsgay +1
We revisit the integrability of quantum circuits constructed from two-qubit unitary gates that satisfy the Yang-Baxter equation. A brickwork arrangement of typically corres…
Weak ergodicity breaking with isolated integrable sectors
Hosho Katsura, Chihiro Matsui, Chiara Paletta +1
We consider spin chain models with local Hamiltonians that display weak ergodicity breaking. In these models, the majority of the eigenstates are thermal, but there is a distinguis…
Integrability of open boundary driven quantum circuits
Chiara Paletta, Tomaž Prosen
In this paper, we address the problem of Yang-Baxter integrability of doubled quantum circuit of qubits (spins 1/2) with open boundary conditions where the two circuit replicas are…
