Non-decomposable quantum dynamical semigroups and bound entangled states

Fabio Benatti, Roberto Floreanini, Marco Piani

We use open quantum system techniques to construct one-parameter semigroups of positive maps and apply them to study the entanglement properties of a class of 16-dimensional densit…

Continuous Limit of Discrete Sawtooth Maps and its Algebraic Framework

Fabio Benatti, Valerio Cappellini

We study the presence of a logarithmic time scale in discrete approximations of Sawtooth Maps on the 2--torus. The techniques used are suggested by quantum mechanical similarities,…

Gluino Annihilations and Neutralino Dark Matter

S. Profumo, C. E. Yaguna

We consider supersymmetric scenarios, compatible with all cosmological and phenomenological requirements, where the lightest SUSY particles (LSPs) are the neutralino and a quasi de…

Vacuum energy momentum tensor in (2+1) NC scalar field theory

P. Nicolini

A scalar field in (2+1) dimensional Minkowski space-time is considered. Postulating noncommutative spatial coordinates, one is able to determine the (UV finite) vacuum expectation…

General criterion for the entanglement of two indistinguishable particles

GianCarlo Ghirardi, Luca Marinatto

We relate the notion of entanglement for quantum systems composed of two identical constituents to the impossibility of attributing a complete set of properties to both particles.…
