We construct general models for holographic superconductivity parametrized by three couplings which are functions of a real scalar field and show that under general assumptions they describe superconducting phase transitions. While some features are universal and model independent, important aspects of the quantum critical behavior strongly depend on the choice of couplings, such as the order of the phase transition and critical exponents of second-order phase transitions. In particular, we…

Holographic superconductor models in the non-minimal derivative coupling theory

We study a general class of holographic superconductor models via the Stuckelberg mechanism in the non-minimal derivative coupling theory in which the charged scalar field is kinetically coupling to

Analytic holographic superconductor

We investigate a holographic superconductor that admits an analytic treatment near the phase transition. In the dual 3+1-dimensional field theory, the phase transition occurs when a scalar operator

Phenomenological models of holographic superconductors and hall currents

We study general models of holographic superconductivity parametrized by four arbitrary functions of a neutral scalar field of the bulk theory. The models can accommodate several features of real

Introduction to holographic superconductor models

In the last years it has been shown that some properties of strongly coupled superconductors can be potentially described by classical general relativity living in one higher dimension, which is

Holographic model of a two-band superconductor

We construct a holographic two-band superconductor model with interband Josephson coupling. We investigate the effects the Josephson coupling has on the superconducting condensates and the critical

Holographic competition of phases and superconductivity

A bstractWe use a holographic theory to model and study the competition of four phases: an antiferromagnetic phase, a superconducting phase, a metallic phase and a striped phase, using as control

Holographic superconductors from Einstein-Maxwell-Dilaton gravity

We construct holographic superconductors from Einstein-Maxwell-dilaton gravity in 3 + 1 dimensions with two adjustable couplings α and the charge q carried by the scalar field. For the values of α



A general class of holographic superconductors

We introduce a simple generalization of the basic holographic superconductor model in which the spontaneous breaking of a global U(1) symmetry occurs via the Stückelberg mechanism. This more general

Holographic approach to phase transitions

We provide a description of phase transitions at finite temperature in strongly coupled field theories using holography. For this purpose, we introduce a general class of gravity duals to

Universality class of holographic superconductors

We study ''holographic superconductors'' in various spacetime dimensions. We compute most of the static critical exponents in the linear perturbations and show that they take the standard mean-field

Holographic superconductors with various condensates

We extend earlier treatments of holographic superconductors by studying cases where operators of different dimension condense in both 2+1 and 3+1 superconductors. We also compute a correlation

Ground states of holographic superconductors

We investigate the ground states of the Abelian Higgs model in AdS{sub 4} with various choices of parameters, and with no deformations in the ultraviolet other than a chemical potential for the

Building a holographic superconductor.

It is shown that a simple gravitational theory can provide a holographically dual description of a superconductor and evidence is found that the condensate consists of pairs of quasiparticles.

Holographic Superconductors

: It has been shown that a gravitational dual to a superconductor can be obtained by coupling anti-de Sitter gravity to a Maxwell field and charged scalar. We review our earlier analysis of this

Holographic superconductors with higher curvature corrections

We study (3+1)-dimensional holographic superconductors in Einstein-Gauss-Bonnet gravity both numerically and analytically. It is found that higher curvature corrections make condensation harder. We

Low-temperature behavior of the Abelian Higgs model in Anti-de Sitter space

We explore the low-temperature behavior of the Abelian Higgs model in AdS4, away from the probe limit in which back-reaction of matter fields on the metric can be neglected. Over a significant range

Superconductors from superstrings.

We establish that in a large class of strongly coupled (3+1)-dimensional N=1 quiver conformal field theories with gravity duals, adding a chemical potential for the R charge leads to the existence of
