A sufficient condition for complete positivity

The evolution equations of the statistical operator are (often) subject to the natural request of complete positivity (CP).

Non-Markovianity - Semigroup Definition

A way to construct a dynamics which seems to present memory effects will be presented. A specific example will be presented and studied.

Basic Concepts on Ergodic Teory

In this talk (one or two talks depending on how it goes) I will outline basic concepts about ergodic theory, Boltzmann's ergodic hyphothesis and the concept of a deterministic system behaving in

Gisin's theorem and no-faster-than-light signaling

One way to study possible theories beyond standard quantum theory is to modify Schrodinger equation by adding new terms.

Faster than light I: Axiomatic foundations of special relativity, tachyons, and causal paradoxes

This talk is supposed to be the first in a series, discussing the problem of faster-than-light signalling appearing in realistic quantum theories as a consequence of quantum non-locality. We review h

Gross-Pitaevskii equation and superfluidity in Bose-Einstein condensates

We will see a brief review on the following topics: i) Gross - Pitaevskii equation and Bogoliubov theory of a Bose - Einstein condesate. ii) Superfluidity, hydrodynamics and their relation with B

Decoherence effects on 1D quasi-condensates

In the last yers, several experimental works have observed decoherence effects on low dimensional ultracold atoms systems.

Light slower than the speed of light

Recently it has been claimed that in presence of a classical gravitational potential the speed of light gets a correction coming from the interaction of virtual electron-positron pairs with the gravit
