Abstract
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.
