摘要:

基于Sturm-Liouville本征值问题,我们发展了一种研究全息超导体激发态的一般解析方法。通过在试探函数的展开式中加入更多的高阶项,我们观察到解析结果与数值结果吻合得很好,这表明Sturm-Liouville方法对于研究全息超导体是非常有效的,即使我们考虑了激发态.对于全息s波和p波模型,我们发现激发态的临界温度比相应的基态低,并且相邻态之间的无量纲临界化学势差约为5。此外,我们还解析地证实了具有激发态的全息超导相变属于二级相变,这一结果可以用来支持s波和p波超导体的数值结果.

英文摘要:

Based on the Sturm-Liouville eigenvalue problem, we develop a general analytic technique to investigate the excited states of the holographic superconductors. By including more higher order terms in the expansion of the trial function, we observe that the analytic results agree well with the numeric data, which indicates that the Sturm-Liouville method is very powerful to study the holographic superconductors even if we consider the excited states. For both the holographic s-wave and p-wave models, we find that the excited state has a lower critical temperature than the corresponding ground state and the difference of the dimensionless critical chemical potential between the consecutive states is around 5. Moreover, we analytically confirm that the holographic superconductor phase transition with the excited states belongs to the second order, which can be used to back up the numerical findings for both s-wave and p-wave superconductors.
