On the lattice structure of probability spaces in quantum mechanics
Federico Holik, César Massri, Leandro Zuberman +1
Let C be the set of all possible quantum states. We study the convex subsets of C with attention focused on the lattice theoretical structure of these convex subsets and, as a resu…
Short periodic orbit approach to resonances and the fractal Weyl law
J. M. Pedrosa, D. Wisniacki, G. G. Carlo +1
We investigate the properties of the semiclassical short periodic orbit approach for the study of open quantum maps that was recently introduced in [M. Novaes, J.M. Pedrosa, D. Wis…
Quantal effects and MaxEnt
Federico Holik, Angel Plastino
Convex operational models (COMs) are considered as great extrapolations to larger settings of any statistical theory. In this article we generalize the maximum entropy principle (M…
Convex politopes and quantum separability
Fedrico Holik, Angel Plastino
We advance a novel perspective of the entanglement issue that appeals to the Schlienz-Mahler measure [Phys. Rev. A 52, 4396 (1995)]. Related to it, we propose an criterium based on…
The complexity of energy eigenstates as a mechanism for equilibration
Lluis Masanes, Augusto J. Roncaglia, Antonio Acin
Understanding the mechanisms responsible for the equilibration of isolated quantum many-body systems is a long-standing open problem. In this work we obtain a statistical relations…
Casimir Force for Absorbing Media in an Open Quantum System Framework: Scalar Model
Fernando C. Lombardo, Francisco D. Mazzitelli, Adrian E. Rubio Lopez
In this article we compute the Casimir force between two finite-width mirrors at finite temperature, working in a simplified model in 1+1 dimensions. The mirrors, considered as dis…
