质量引力对$p$波全息超导体的影响

Effects of massive gravity on $p$-wave holographic superconductor

Cao H. Nam

摘要:

本文在质量引力的框架下,在探测极限下,对$p$波全息超导体进行了解析研究。得到了超导体的临界温度、凝聚算符的值以及超导相和正常相的自由能之差的解析表达式。我们研究了这些量在引力子质量存在下的行为,发现引力子质量几乎依赖于大质量引力耦合的符号。随着质量引力耦合的增大(减小)或质量引力耦合为充分正(负)时引力子质量的增大,临界温度变(低)高,凝聚值变(大)小。这一事实对应于超导体相是(更多)更少的结晶。

英文摘要:

In this paper, we have analytically investigated $p$-wave holographic superconductor in the framework of massive gravity in the probe limit. We obtained the analytical expressions for the critical temperature, the value of the condensate operator, and the difference of the free energy between the superconductor and normal phases. We studied the behavior of these quantities in the presence of the mass of graviton, which is found to be dependent almost on the sign of the massive gravity couplings. The critical temperature becomes (lower)higher and the condensate value gets (larger)smaller with (decreasing)increasing the massive gravity couplings or increasing the mass of graviton with the sufficiently (negative)positive massive gravity couplings. This fact corresponds to that the superconductor phase is (more)less thermodynamically favored.
