Three dimensional origin of Godel spacetimes and black holes
Maximo Banados, Glenn Barnich, Geoffrey Compere +1
We construct Godel-type black hole and particle solutions to Einstein-Maxwell theory in 2+1 dimensions with a negative cosmological constant and a Chern-Simons term. On-shell, the…
The 2+1 charged black hole in topologically massive Electrodynamics
T. Andrade, M. Banados, R. Benguria +1
The 2+1 black hole coupled to a Maxwell field can be charged in two different ways. On the one hand, it can support a Coulomb field whose potential grows logarithmically in the rad…
Decay of the Cosmological Constant. Equivalence of Quantum Tunneling and Thermal Activation in Two Spacetime Dimensions
Andres Gomberoff, Marc Henneaux, Claudio Teitelboim
We study the decay of the cosmological constant in two spacetime dimensions through production of pairs. We show that the same nucleation process looks as quantum mechanical tunnel…
