Euclidean operator growth and quantum chaos
Alexander Avdoshkin, Anatoly Dymarsky
We consider growth of local operators under Euclidean time evolution in lattice systems with local interactions. We derive rigorous bounds on the operator norm growth and then proc…

Rate of cluster decomposition via Fermat-Steiner point
Alexander Avdoshkin, Lev Astrakhantsev, Anatoly Dymarsky +1
In quantum field theory with a mass gap correlation function between two spatially separated operators decays exponentially with the distance. This fundamental result immediately i…
