# Seminars and Journal Clubs

Friday, October 24, 2014 Sandro Donadi ## Bohmian MechanicsIn this seminar we will give an introduction to Bohmian Mechanics (also known as De Broglie-Bohm theory). |
Friday, October 17, 2014 Marco Bilardello ## Gross-Pitaevskii equation and superfluidity in Bose-Einstein condensatesWe 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 |

Friday, September 12, 2014 Marco Bilardello ## Decoherence effects on 1D quasi-condensatesIn the last yers, several experimental works have observed decoherence effects on low dimensional ultracold atoms systems. |
Thursday, July 24, 2014 André Großardt ## Light slower than the speed of lightRecently 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 |

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. |
