N-dimensional static and evolving Lorentzian wormholes with cosmological constant
Mauricio Cataldo, Paola Meza, Paul Minning
We present a family of static and evolving spherically symmetric Lorentzian wormhole solutions in N+1 dimensional Einstein gravity. In general, for static wormholes, we require tha…
On a class of scaling FRW cosmological models
Mauricio Cataldo, Fabiola Arevalo, Paul Minning
We study Friedmann-Robertson-Walker cosmological models with matter content composed of two perfect fluids and , with barotropic pressure densities …
Standard General Relativity from Chern-Simons Gravity
Fernando Izaurieta, Paul Minning, Alfredo Pérez +2
Chern-Simons models for gravity are interesting because they provide with a truly gauge-invariant action principle in the fiber-bundle sense. So far, their main drawback has largel…
Evolving Lorentzian wormholes supported by phantom matter and cosmological constant
Mauricio Cataldo, Sergio del Campo, Paul Minning +1
In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made of phantom energy in the presence of a cosmological constant. We derive analytical…
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…
Supersymmetry, quark confinement and the harmonic oscillator
S. A. Bruce, P. C. Minning
We study some quantum systems described by noncanonical commutation relations formally expressed as [q,p]=ihbar(I + chi H), where H is the associated (harmonic oscillator-like) Ham…
