研究了四维AdS后孔背景下的一般全息超导体模型。我们探讨了标量凝聚过程中相变的性质，得出了在各种标量场质量大于零的情况下，较低的临界温度与较深的凝聚间隙的对应关系。我们还研究了模型参数对相变的影响，发现当模型参数高于阈值时，该模型允许以非负标量质量发生一阶相变。最后，我们研究了反反应和标量质量对阈值模型参数的影响。
We study a general holographic superconductor model in four dimensional AdS back hole background. We explore the properties of the phase transitions in the scalar condensation and conclude the correspondence of a lower critical temperature with a deeper condensation gap holds with various scalar field mass above zero. We also examine the effects of the model parameters on the phase transition and find that this model allows first order phase transitions to occur with non-negative scalar mass when the model parameter is above a threshold value. Finally, we study the effects of the backreaction and scalar mass on the threshold model parameters.
