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

The conditional wave function and its dynamics

At the end of the previous seminar we quickly introduced the concept of conditional wave function.

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

Just a theorem about not completely positive maps

Imagine you are given a nonlinear stochastic Schrödinger equation which evolves in a markovian way and satisfies very general physical requirements, such as the assumption of no-faster-than-light sign

Interaction picture in QFT and Haag's theorem

We will discuss on interaction picture in quantum field theory and how Haag's theorem proves that this approach cannot be used to describe interacting fields.

Quantum linear Boltzmann equation in the weak coupling regime

In this seminar, we deal with the dynamics of a test particle interacting with a low density background gas.
