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…
Translations and reflections on the torus: Identities for discrete Wigner functions and transforms
Marcos Saraceno, Alfredo M. Ozorio de Almeida
A finite Hilbert space can be associated to a periodic phase space, that is, a torus. A finite subgroup of operators corresponding to reflections and translations on the torus form…
Chaos signatures in the short and long time behavior of the out-of-time ordered correlator
Ignacio García-Mata, Marcos Saraceno, Rodolfo A. Jalabert +2
Two properties are needed for a classical system to be chaotic: exponential stretching and mixing. Recently, out-of-time order correlators were proposed as a measure of chaos in a…
Phase-space representations of SIC-POVM fiducial states
Marcos Saraceno, Leonardo Ermann, Cecilia Cormick
The problem of finding symmetric informationally complete POVMs (SIC-POVMs) has been solved numerically for all dimensions up to 67 (A.J. Scott and M. Grassl, {\it J. Math. Phy…
Representation of superoperators in double phase space
Marcos Saraceno, Alfredo M. Ozorio de Almeida
Operators in quantum mechanics - either observables, density or evolution operators, unitary or not - can be represented by c-numbers in operator bases. The position and momentum b…
Transient features of quantum open maps
Leonardo Ermann, Gabriel G. Carlo, Juan M. Pedrosa +1
We study families of open chaotic maps that classically share the same asymptotic properties -- forward and backwards trapped sets, repeller dimensions, escape rate -- but differ i…
