Phase Diagram of a Holographic Superconductor Model with s-wave and d-wave

Understand

We consider a holographic model with a scalar field, a tensor field and a direct coupling between them as a superconductor with an s-wave and a d-wave.

• We find a rich phase structure in the model.
• The model exhibits a phase of coexistence of the s-wave and the d-wave, or a phase of an order competition.
• Furthermore, it has a triple point.
