Evolving Lorentzian wormholes supported by phantom matter with constant state parameters
Mauricio Cataldo, Pedro Labrana, Sergio del Campo +2
In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made out of phantom energy. We show that this exotic source can support the existence of…
Interacting cosmic fluids in power-law Friedmann-Robertson-Walker cosmological models
Mauricio Cataldo, Patricio Mella, Paul Minning +1
We provide a detailed description for power--law scaling Friedmann-Robertson-Walker cosmological scenarios dominated by two interacting perfect fluid components during the expansio…
Unifying dark components and crossing the phantom divide with a classical Dirac field
Mauricio Cataldo, Luis P. Chimento
In this paper we consider a spatially flat Friedmann-Robertson-Walker (FRW) cosmological model whit cosmological constant, containing a stiff fluid and a classical Dirac field. The…
The Electrically Charged Extreme BTZ Black Hole with Self (Anti-self) Dual Maxwell Field
Mauricio Cataldo, Patricio Salgado
Recently M. Kamata and T. Koikawa claimed to obtain the charged version of the spinning BTZ black hole solution by assuming an (anti-) self dual condition imposed on the orthonorma…
Conformal Fourth-Rank Gravity
Victor Tapia, A. L. Marrakchi, M. Cataldo
We consider the consequences of describing the metric properties of space- time through a quartic line element . The associated "metric" is a fourth-…
