Interpolating geometries and the stretched dS$_2$ horizon
Abstract
We investigate dilaton-gravity models whose solutions contain a large portion of the static patch of dS. The thermodynamic properties of these theories are considered both in the presence of a finite Dirichlet wall, as well as for asymptotically near-AdS boundaries. We show that under certain circumstances such geometries, including those endowed with an asymptotically near-AdS boundary, can be locally and even globally thermodynamically stable within particular temperature regimes. First order phase transitions reminiscent of the Hawking-Page transition are discussed. For judiciously chosen models, the near-AdS boundary can be viewed as a completion of the stretched cosmological dS horizon. We speculate on candidate microphysical models.
