We study holographic superconductors analytically by using the Ginzburg–Landau action with the 𝛾-quartic term |Ψ|4. Our results show that 𝛾-term plays a role in the scalar condensation. It is found that the system displays two kinds of critical temperatures. One is independent of 𝛾. But the other increases with increasing 𝛾, which suggests the onset of easier condensation.

The frequency-dependent conductivity is obtained for the holographic superconductor by using the Ginzburg–Landau theory with a |Ψ|4 term. Our results show that |Ψ|4 term plays a role in the low-temperature behaviour of the conductivity.

Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
