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…
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…
Ground state of composite bosons in low-dimensional graphs
Cecilia Cormick, Leonardo Ermann
We consider a system of composite bosons given by strongly bound fermion pairs tunneling through sites that form a low-dimensional network. It has been shown that the ground state…
Fokker-Planck treatment of nonlinearities in the dispersive coupling of an ion and an optical cavity
Alan Kahan, Leonardo Ermann, Marcos Saraceno +1
We complement previous studies of an ion coupled with an optical cavity in the dispersive regime, for a model which exhibits bistability of different configurations in the semiclas…
Loschmidt echo and Poincaré recurrences of entanglement
Leonardo Ermann, Klaus M. Frahm, Dima L Shepelyansky
We study numerically the properties of entanglement of two interacting, or noninteracting, particles evolving in a regime of quantum chaos in the quantum Chirikov standard map. Suc…
