Tuesday, July 15, 2014 Matteo Caiaffa ## Just a theorem about not completely positive mapsImagine 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 |
Friday, July 11, 2014 Marco Bilardello ## Interaction picture in QFT and Haag's theoremWe 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. |

Friday, July 4, 2014 Andrea Smirne ## Quantum linear Boltzmann equation in the weak coupling regimeIn this seminar, we deal with the dynamics of a test particle interacting with a low density background gas. |
Friday, June 27, 2014 Giulio Gasbarri ## A derivation of the Gallis-Flemming equation by Hartree Variational MethodWe 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 |

Friday, June 13, 2014 Marko Toros ## Introduction to QFT in Curved SpacetimeWe 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. |
Wednesday, April 16, 2014 Mohammad Bahrami ## On the meaning of wave functionQuestions on the meaning of wave function are still very puzzling in the spite of remarkable success of quantum predictions. |

Friday, April 11, 2014 Matteo Caiaffa ## 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. |
Friday, April 4, 2014 Matteo Carlesso ## Caldeira-Leggett Model - Two different approaches for an ohmic environementTwo different approaches of the well-known Caldeira Legget model will be presented and discussed. |

Friday, March 28, 2014 André Großardt ## Self-gravitating quantum systems: Schrödinger-Newton dynamics and experimental testsThis 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 |
