Complex spacing ratio statistics in the partially open asymmetric quantum baker map
Leonardo Ermann, Pablo Sesin, Alejandro M. F. Rivas +2
We study the complex eigenvalue statistics of the asymmetric quantum baker map with partial projective openings. The classical asymmetric baker map, with its discontinuity at $q=2/…
Ideal Gas Law for a Quantum Particle
Alejandro M. F Rivas, Eduardo G. Vergini, Leonardo Ermann +1
The question of how classical thermodynamic laws emerge from the underlying quantum substrate lies at the foundations of physics. Here, we examine the validity of the ideal gas law…
Spectral truncation of out-of-time-ordered correlators in dissipative system
Pablo D. Bergamasco, Gabriel G. Carlo, Alejandro M. F. Rivas
Out-of-time-ordered correlators (OTOCs) have emerged as powerful tools for diagnosing quantum chaos and information scrambling. While extensively studied in closed quantum systems,…
Exploring quantum localization with machine learning
J. Montes, Lenoardo Ermann, Alejandro M. F. Rivas +2
We introduce an efficient neural network (NN) architecture for classifying wave functions in terms of their localization. Our approach integrates a versatile quantum phase space pa…
Quantum Lyapunov exponent in dissipative systems
Pablo D. Bergamasco, Gabriel G. Carlo, Alejandro M. F. Rivas
The out-of-time order correlator (OTOC) has been widely studied in closed quantum systems. However, there are very few studies for open systems and they are mainly focused on isola…
Relevant OTOC operators: footprints of the classical dynamics
Pablo D. Bergamasco, Gabriel G. Carlo, Alejandro M. F. Rivas
The out-of-time order correlator (OTOC) has recently become relevant in different areas where it has been linked to scrambling of quantum information and entanglement. It has also…
