Abstract
In this letter, I investigate the deformation of the ModMax theory, as a unique Lagrangian of non-linear electrodynamics preserving both conformal and electromagnetic-duality invariance, under $T-T^{bar}$-like
flows. I show that the deformed theory is the generalized non-linear Born-Infeld electrodynamics. Being inspired by the invaria ...

Thermodynamic ensembles with cosmological horizons

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 ...
