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.

A derivation of the Gallis-Flemming equation by Hartree Variational Method

We will show a derivation of the well known Gallis-Flemming equation by the use of the variational Hartree method and we will also discuss on the possibility to extend this method in the non dissipat

Introduction to QFT in Curved Spacetime

We first discuss classical General Relativity with particular focus on conservation laws and symmetries. We then look at quantum field theory and the role of Poincaré symmetries.

On the meaning of wave function

Questions on the meaning of wave function are still very puzzling in the spite of remarkable success of quantum predictions.

What is Complete Positivity? No, really… what's this thing about?

The talk concerns with an introduction to the theory of dynamical maps in Banach spaces, which are the main instruments around which my master thesis will be written.

Self-gravitating quantum systems: Schrödinger-Newton dynamics and experimental tests

This talk is supposed to review the so called "Schrödinger-Newton equation", a nonlinear Schrödinger-equation which provides a falsifiable hypothesis for how a quantum system in a non-classi
