General approach to the Lagrangian ambiguity in gravity
G. A. Carvalho, F. Rocha, H. O. Oliveira +1
The gravity is a theory whose gravitational action depends arbitrarily on the Ricci scalar, , and the trace of the stress-energy tensor, ; its field equations also d…
Study of the charged super-Chandrasekhar limiting mass white dwarfs in the gravity
F. Rocha, G. A. Carvalho, D. Deb +1
The equilibrium configuration of white dwarfs composed of a charged perfect fluid are investigated in the context of the gravity, for which and …
Fermion correlators in non-abelian holographic superconductors
Steven S. Gubser, Fabio D. Rocha, Amos Yarom
We consider fermion correlators in non-abelian holographic superconductors. The spectral function of the fermions exhibits several interesting features such as support in displaced…
Peculiar properties of a charged dilatonic black hole in AdS_5
Steven S. Gubser, Fabio D. Rocha
We study a charged dilatonic black hole in AdS_5, derived from a lagrangian involving a gauge field whose kinetic term is modified by the exponential of a neutral scalar. This blac…
Normalizable fermion modes in a holographic superconductor
Steven S. Gubser, Fabio D. Rocha, Pedro Talavera
We consider fermions in a zero-temperature superconducting anti-de Sitter domain wall solution and find continuous bands of normal modes. These bands can be either partially filled…
Quantum critical superconductors in string theory and M-theory
Steven S. Gubser, Silviu S. Pufu, Fabio D. Rocha
We construct zero-temperature solutions of supergravity theories in five and four dimensions which interpolate between two copies of anti-de Sitter space, one of which preserves an…
