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,…
