SUMMARY:Seminar by Claudia Frugiuele (INFN\, Milan): "Is the large uncertainty of deltaCP fundamentally encoded in the neutrino quantum state?"
DESCRIPTION:Title: “Is the large uncertainty of deltaCP fundamentally encoded in the neutrino quantum state?” \nSpeaker: Seminar Claudia Frugiuele (INFN\, Milan) \nVenue & Time: Red Room / 15:00 \nAbstract: Quantum estimation theory provides a framework to quantify the ultimate precision limits for parameter estimation in physical systems. I will introduce its basic concepts and apply them to neutrino oscillations\, focusing on the estimation of the PMNS parameters. \nA central puzzle is why the CP\, violating phase δCP remains significantly less constrained than the other mixing parameters. Using quantum estimation tools\, I will  show that this limitation is not due to a lack of information encoded in the neutrino quantum state. Instead\, it arises from the suboptimal nature of standard flavor measurements\, particularly near the first oscillation peak. \nI will then compare the achievable precision with that of other mixing parameters\, for which current measurements are already close to optimal. \nI will conclude with the case of astrophysical neutrinos\, where the same tools quantify how much information on the PMNS parameters and on the source composition is lost to phase averaging and to flavor-only measurements.

SUMMARY:Old Journal Club by Michelangelo Tartaglia: “Ordering\, metastability and phase transitions in two-dimensional systems (J M Kosterlitz and D J Thouless)”
DESCRIPTION:Title: “Ordering\, metastability and phase transitions in two-dimensional systems (J M Kosterlitz and D J Thouless)” \nSpeaker: Alfred Benedito \nVenue & Time: Blue Room / 17:00 \nAbstract: A new definition of order called topological order is proposed for two-dimensional systems in which no long-range order of the conventional type exists. The possibility of a phase transition characterized by a change in the response of the system to an external perturbation is discussed in the context of a mean field type of approximation. The critical behaviour found in this model displays very weak singularities. The application of these ideas to the xy model of magnetism\, the solid-liquid transition\, and the neutral superfluid are discussed. This type of phase transition cannot occur in a superconductor nor in a Heisenberg ferromagnet. for reasons that are given.
