Loschmidt echo approach to Krylov-subspace approximation error estimation
Julian Ruffinelli, Emiliano Fortes, Martín Larocca +1
The Krylov subspace method is a standard approach to approximate quantum evolution, allowing to treat systems with large Hilbert spaces. Although its application is general, and su…
Signatures of quantum chaos transition in short spin chains
Emiliano M. Fortes, Ignacio García-Mata, Rodolfo A. Jalabert +1
The non-integrability of quantum systems, often associated with chaotic behavior, is a concept typically applied to cases with a high-dimensional Hilbert space Among different indi…
Gauging classical and quantum integrability through out-of-time ordered correlators
Emiliano M. Fortes, Ignacio García-Mata, Rodolfo A. Jalabert +1
Out-of-time-order correlators (OTOCs) have been proposed as a probe of chaos in quantum mechanics, on the basis of their short-time exponential growth found in some particular set-…
