Quantum-corrected black holes and naked singularities in (2+1)-dimensions
Marc Casals, Alessandro Fabbri, Cristián Martínez +1
We analytically investigate the pertubative effects of a quantum conformally-coupled scalar field on rotating (2+1)-dimensional black holes and naked singularities. In both cases w…
Geodesic Structure of Naked Singularities in AdS Spacetime
Cristián Martínez, Nicolás Parra, Nicolás Valdés +1
We present a complete study of the geodesics around naked singularities in AdS, the three-dimensional anti-de Sitter spacetime. These stationary spacetimes, characterized by tw…
Quantum dress for a naked singularity
Marc Casals, Alessandro Fabbri, Cristián Martínez +1
We investigate semiclassical backreaction on a conical naked singularity space-time with a negative cosmological constant in (2+1)-dimensions. In particular, we calculate the renor…
Gravitational Cheshire effect: Nonminimally coupled scalar fields may not curve spacetime
Eloy Ayón-Beato, Cristián Martínez, Ricardo Troncoso +1
It is shown that flat spacetime can be dressed with a real scalar field that satisfies the nonlinear Klein-Gordon equation without curving spacetime. Surprisingly, this possibility…
