Holographic p-wave superconductivity from higher derivative theory

We construct a holographic SU(2) p-wave superconductor model withWeyl corrections. The high derivative (HD) terms do not seem to spoil the generation of the pwave superconducting phase. We mainly study the properties ofAC conductivity, which is absent in holographic SU(2) p-wave superconductor with Weyl corrections. The conductivities in superconducting phase exhibit obvious anisotropic behaviors. Along y direction, the conductivity syy is similar to that of holographic s-wave superconductor. The superconducting energy gap exhibits a wide extension. For the conductivity sxx along x direction, the behaviors of the real part in the normal state are closely similar to that of sigma(yy). However, the anisotropy of the conductivity obviously shows up in the superconducting phase. A Drude-like peak at low frequency emerges in Re sigma(xx) once the system enters into the superconducting phase, regardless of the behaviors in normal state.

Automated summary

The research reveals that in the holographic SU(2) p-wave superconductor model with Weyl corrections, the conductivity in the superconducting phase exhibits obvious anisotropic behaviors. In the superconducting phase, a behavior similar to a Drude peak emerges in the real part of the conductivity, regardless of the behaviors in the normal state.
