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…
Hierarchical generalization of dual unitarity
Xie-Hang Yu, Zhiyuan Wang, Pavel Kos
Quantum dynamics with local interactions in lattice models display rich physics, but is notoriously hard to study. Dual-unitary circuits allow for exact answers to interesting phys…
Localised Dynamics in the Floquet Quantum East Model
Bruno Bertini, Pavel Kos, Tomaz Prosen
We introduce and study the discrete-time version of the Quantum East model, an interacting quantum spin chain inspired by simple kinetically constrained models of classical glasses…
Scrambling is Necessary but Not Sufficient for Chaos
Neil Dowling, Pavel Kos, Kavan Modi
We show that out-of-time-order correlators (OTOCs) constitute a probe for Local-Operator Entanglement (LOE). There is strong evidence that a volumetric growth of LOE is a faithful…
