论文摘要
我们重新考虑了全息超导体的间隙结构的角度依赖性，到目前为止尚未仔细处理。对于向量场模型，我们表明可正常化的基态处于P波状态，因为S波状态不可正常化。另一方面，在标量订单模型中，基态位于$ S $波。在这些模型中明确构建了角度依赖性间隙函数。我们还建议对向量顺序进行修改的ANSATZ，它使该顺序可以讨论$ p_ {x} \ pm ip_ {y} $ gap的顺序，到目前为止还不可能。我们还通过分析研究了附近的临界温度和间隙的行为。有趣的是，对于库珀对操作员的固定保形维度，向量模型中的临界温度高于标量模型的临界温度。
We reconsider the angular dependence in gap structure of holographic superconductors, which has not been treated carefully so far. For the vector field model, we show that the normalizable ground state is in the p-wave state because s-wave state is not normalizable. On the other hand, in the scalar order model, the ground state is in the $s$-wave. The angle dependent gap function is explicitly constructed in these models. We also suggest the modified ansatz of the vector order which enables to discuss the order $p_{x}\pm ip_{y}$ gap, which has not been possible so far. We have also analytically investigated the critical temperature and the behavior of the gap near there. Interestingly, for the fixed conformal dimension of the Cooper pair operator, the critical temperature in vector model is higher than that of the scalar model.
