The conical singularity method and the energy-momentum tensor near the black hole horizon using the Kruskal coordinates
M. Alves
We apply the conical singularity method to the two dimensional version of the Schwarzschild metric to obtain the Kruskal coordinates of the black hole in a very simple and direct w…
Time-dependent cosmological constant in the Jackiw-Teitelboim cosmology
M. Alves, J. Barcelos-Neto, M. Novello +1
We study the obtainment of a time-dependent cosmological constant at D=2 in a model based on the Jackiw-Teitelboim cosmology. We show that the cosmological term goes to zero asympt…
Black hole formation in bidimensional dilaton gravity coupled to scalar matter systems
M. Alves, D. Bazeia, V. B. Bezerra
This work deals with the formation of black hole in bidimensional dilaton gravity coupled to scalar matter fields. We investigate two scalar matter systems, one described by a sixt…
Hawking Radiation in the Dilaton Gravity with a Non-Minimally Coupled Scalar Field
M. Alves
We discuss the two-dimensional dilaton gravity with a scalar field as the source matter where the coupling with the gravity is given, besides the minimal one, through an external f…
Dilaton Gravity with a Non-Minimally Coupled Scalar Field
Marcelo Alves
We discuss the two-dimensional dilaton gravity with a scalar field as the source matter. The coupling between the gravity and the scalar, massless, field is presented in an unusual…
