Can conformal Transformations change the fate of 2D black holes?
J. Cruz, A. Fabbri, J. Navarro-Salas
By using a classical Liouville-type model of two dimensional dilaton gravity we show that the one-loop theory implies that the fate of a black hole depends on the conformal frame.…
Free Fields for Chiral 2D Dilaton Gravity
J. Cruz, J. Navarro-Salas, M. Navarro
We give an explicit canonical transformation which transforms a generic chiral 2D dilaton gravity model into a free field theory.
Hidden conformal symmetry of a massive scalar field in 2-dimensional Anti-De Sitter space
J. Cruz
We show that a massive scalar field on a 2-dimensional Anti-De Sitter space can be mapped by means of a time-dependent canonical transformation into a massless free field theory wh…
Free Field Realization of Cylindrically Symmetric Einstein Gravity
J. Cruz, A. Mikovic, J. Navarro-Salas
Cylindrically reduced Einstein gravity can be regarded as an sigma model coupled to 2D dilaton gravity. By using the corresponding 2D diffeomorphism algebra of cons…
