at: 13:15 room S2.29  abstract: We propose a unified description of two important phenomena: color confinement in large$N$ gauge theory, and BoseEinstein condensation (BEC). The key lies in relating standard criteria, based on offdiagonal long range order (ODLRO) for BEC and the Polyakov loop for gauge theory: the constant offset of the distribution of the phases of the Polyakov loop corresponds to ODLRO. Indistinguishability associated with the symmetry group  SU(N) or O(N) in gauge theory, and S_N permutations in the system of identical bosons  is crucial in either case. This viewpoint may have implications for confinement at finite N, and for quantum gravity via gauge/gravity duality. As a byproduct, we obtain a characterization of the partiallyconfined/partiallydeconfined phase at finite coupling: the constant offset of the distribution of the phases of the Polyakov loop is the order parameter. 
Regular Seminar Josh Kirklin (University of Cambridge)
at: 14:00 room GO Jones 610  abstract: Subregion duality is an idea in holography which states that every subregion of the boundary theory has a corresponding subregion in the bulk theory, called the 'entanglement wedge', to which it is dual. In the classical limit of the gravity theory, we expect the fields in the entanglement wedge to permit a Hamiltonian description involving a phase space and Poisson brackets. In this talk, I will describe how this phase space arises from the point of view of the boundary theory. In particular, I will explain how it emerges from measurements of a certain quantum informationtheoretic quantity, known as the 'Uhlmann phase', in the boundary subregion.
