Abstract

Title- dS ₂ as excitation of AdS ₂

We introduce a family of 2D dilaton gravity models with state-dependent constant curvature so that dS ₂ emerges as an excitation of AdS ₂ . Curiously, the strong coupling region corresponds to the asymptotic region geometrically. Apart from these key differences, many features resemble the Almheiri–Polchinski model. We discuss perturbative and non-perturbative thermodynamical stability, bubble nucleation through matter shockwaves, and semiclassical backreaction effects. In some of these models, we find that low temperatures are dominated by AdS ₂ but high temperatures are dominated by dS ₂ , concurrent with a recent proposal by Susskind.
