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…
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…
Operator Entanglement in Local Quantum Circuits I: Chaotic Dual-Unitary Circuits
Bruno Bertini, Pavel Kos, Tomaz Prosen
The entanglement in operator space is a well established measure for the complexity of the quantum many-body dynamics. In particular, that of local operators has recently been prop…
Exact Correlation Functions for Dual-Unitary Lattice Models in 1+1 Dimensions
Bruno Bertini, Pavel Kos, Tomaz Prosen
We consider a class of quantum lattice models in dimensions represented as local quantum circuits that enjoy a particular "dual-unitarity" property. In essence, this property…
Entanglement spreading in a minimal model of maximal many-body quantum chaos
Bruno Bertini, Pavel Kos, Tomaz Prosen
The spreading of entanglement in out-of-equilibrium quantum systems is currently at the centre of intense interdisciplinary research efforts involving communities with interests ra…
Exact Spectral Form Factor in a Minimal Model of Many-Body Quantum Chaos
Bruno Bertini, Pavel Kos, Tomaz Prosen
The most general and versatile defining feature of quantum chaotic systems is that they possess an energy spectrum with correlations universally described by random matrix theory (…
