形变四维STU模型中的全息超导体

Holographic superconductor in a deformed four-dimensional STU model

B. Pourhassan, M. M. Bagheri-Mohagheghi

摘要:

本文考虑四维形变STU模型,其中既有电荷又有磁荷。利用AdS/CFT对应,我们研究了全息超导体,得到了电导率和热导率等输运性质。我们得到了黑洞磁荷的输运性质,并将其解释为双场论的磁荷。我们发现,磁荷的存在是具有最大电导率的必要条件,而具有临界电荷(137 e)的磁荷的存在对达到最大超导电性是很重要的.此外,我们还发现热导率随着磁荷的增加而增加。由此可以得出结论,超导性的起源是磁的超导电性。

英文摘要:

In this paper, we consider deformed STU model in four dimensions including both electric and magnetic charges. Using AdS/CFT correspondence, we study holographic superconductor and obtain transport properties like electrical and thermal conductivities. We obtain transport properties in terms of the black hole magnetic charge and interpret it as magnetic monopole of dual field theory. We find that presence of magnetic charge is necessary to have maximum conductivities, and existence of magnetic monopole with a critical charge (137 e) to reach the maximum superconductivity is important. Also, we show that thermal conductivity increases with increasing of magnetic charge. It may be concluded that the origin of superconductivity is magnetic monopole.
