Krylov complexity in quantum field theory, and beyond
Alexander Avdoshkin, Anatoly Dymarsky, Michael Smolkin
We study Krylov complexity in various models of quantum field theory: free massive bosons and fermions on flat space and on spheres, holographic models, and lattice models with the…
Chiral transport in curved spacetime via holography
Alexander Avdoshkin, Rustem Sharipov
We consider a holographic model of strongly interacting plasma with a gravitational anomaly. In this model, we compute parity-odd responses of the system at finite temperature and…
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…
