I show that the deformed theory is the generalized non-linear Born-Infeld electrodynamics. Being inspired by the invaria ... 15:30 - 16:30 Geometry and Topology Seminar Unexpected Dynamical Behaviour, via Anosov-Katok Method School MATHEMATICS

17:00 - 18:00 IPM Holography virtual seminar Thermodynamic ensembles with cosmological horizons School PARTICLES AND ACCELERATORS The entropy of a de Sitter horizon was derived long ago by Gibbons and Hawking via a gravitational partition function. Since there is no boundary at which to define the temperature or energy of the ensemble, the statistical foundation of their approach has remained obscure. To place the statistical ensemble on a firm footing we introduce an artificial "York boundary", with either canonical or microcanonical boundary conditions, as has been done previously for black hole ensembles. The partition function and the density of states are expressed as integrals over paths in the constrained, spherically reduced phase space of pure 3+1 dimensional g ... |
