General theory of measurement with two copies of a quantum state

Ariel Bendersky, Juan Pablo Paz, Marcelo Terra Cunha

We analyze the possible results of the most general measurement on two copies of a quantum state. We show that can label a set of outcomes of such measurement if and only if th…

Distribution of resonances in the quantum open baker map

Juan M. Pedrosa, Gabriel G. Carlo, Diego A. Wisniacki +1

We study relevant features of the spectrum of the quantum open baker map. The opening consists of a cut along the momentum direction of the 2-torus phase space, modelling an op…

Domain-averaged Fermi hole versus regional reduced density matrices: a critical comparison

Diego R. Alcoba, Roberto C. Bochicchio, Luis Lain +1

In their recent work Cooper and Ponec [Phys. Chem. Chem. Phys., 2008, 10, 1319-1329] proposed a ``one-electron approximation to domain-averaged Fermi hole (DAFH)" used in electroni…

Exploring the quantum vacuum with cylinders

F. C. Lombardo, F. D. Mazzitelli, P. I. Villar

We review recent work on the Casimir interaction energy between cylindrical shells. We include proposals for future experiments involving cylinders, such us a null experiment using…

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…
