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…

Gluon self-interaction in the position space in Landau gauge
Gorazd Cvetic, Igor Kondrashuk
We propose a method to treat the three-gluon self-interaction vertex in the position space in D = 4 - 2e dimensions. As an example, we calculate a two-loop contribution to auxiliar…
