Flat space cosmologies in two dimensions - Phase transitions and asymptotic mass-domination
Arjun Bagchi, Daniel Grumiller, Jakob Salzer +2
We study flat space cosmologies in two dimensions by taking the flat space limit of the Achucarro-Ortiz model. We unravel a phase transition between hot flat space and flat space c…

Cosmological constant as confining U(1) charge in two-dimensional dilaton gravity
Daniel Grumiller, Robert McNees, Jakob Salzer
The cosmological constant is treated as a thermodynamical parameter in the framework of two-dimensional dilaton gravity. We find that the cosmological constant behaves as a U(1) ch…
