Scarring in open quantum systems
Diego Wisniacki, Gabriel G. Carlo
We study scarring phenomena in open quantum systems. We show numerical evidence that individual resonance eigenstates of an open quantum system present localization around unstable…
Decoherence induced by Smith-Purcell radiation
Ezequiel Alvarez, Francisco D. Mazzitelli
The interaction between charged particles and the vacuum fluctuations of the electromagnetic field induces decoherence, and therefore affects the contrast of fringes in an interfer…
Decoherence induced by a dynamic spin environment (II): Disentanglement by local system-environment interactions
Cecilia Cormick, Juan Pablo Paz
This article studies the decoherence induced on a system of two qubits by local interactions with a spin chain with nontrivial internal dynamics (governed by an XY Hamiltonian). Sp…
Transport phenomena in the asymmetric quantum multibaker map
Leonardo Ermann, Gabriel G. Carlo, Marcos Saraceno
By studying a modified (unbiased) quantum multibaker map, we were able to obtain a {\em finite} asymptotic quantum current without a classical analogue. This result suggests a gene…
Signatures of non-locality in the first-order coherence of the scattered light
Priscilla Cañizares, Tobias Görler, Juan Pablo Paz +2
The spatial coherence of an atomic wavepacket can be detected in the scattered photons, even when the center-of-mass motion is in the quantum coherent superposition of two distant,…
