Observational constraints on complex quintessence with attractive self-interaction
Belen Carvente, Víctor Jaramillo, Celia Escamilla-Rivera +1
In this paper we consider that dark energy could be described solely by a complex scalar field with a Bose-Einstein condensate-like potential (denoted as CSFDE), that is, with a se…

Traversable -wormholes supported by ghost scalar fields
Belen Carvente, Víctor Jaramillo, Juan Carlos Degollado +2
We present new, asymptotically flat, static, spherically symmetric and traversable wormhole solutions in General Relativity which are supported by a family of ghost scalar fields w…
