Impact of chaos on precursors of quantum criticality
Ignacio García-Mata, Diego A. Wisniacki, Eduardo G. Vergini
Excited-state quantum phase transitions (ESQPTs) are critical phenomena that generate singularities in the spectrum of quantum systems. {For systems with a classical counterpart,}…
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…
Semiclassical theory of out-of-time-order correlators for low-dimensional classically chaotic systems
Rodolfo A. Jalabert, Ignacio García-Mata, Diego A. Wisniacki
The out-of-time-order correlator (OTOC), recently analyzed in several physical contexts, is studied for low-dimensional chaotic systems through semiclassical expansions and numeric…
