Krylov complexity from integrability to chaos

E Rabinovici, A Sánchez-Garrido, R Shir… - Journal of High Energy …, 2022 - Springer
A bstract We apply a notion of quantum complexity, called “Krylov complexity”, to study the
evolution of systems from integrability to chaos. For this purpose we investigate the …
