强耦合系统的磁化率

Magnetic Susceptibility in Strongly Coupled Systems

M. J. Luo

摘要:

在AdS/CFT对应的框架下,通过计算强耦合Maxwell理论中磁化强度的关联函数,研究了大t Hooft耦合下的磁化率.我们证明了在强耦合极限下,磁化率与温度无关,并且是普适的,以体空间的磁导率为单位来度量。与弱耦合系统,泡利顺磁磁化率的比较,也进行了讨论。

英文摘要:

We study the magnetic susceptibility at large 't Hooft coupling by computing the correlation function of the magnetizations in the strongly coupled Maxwell theory in large-N limit with finite temperature and chemical potential, within the framework of the AdS/CFT correspondence. We show that in strong coupling limit the magnetic susceptibility is independent to the temperature and be universal, measured in the unit of magnetic permeability of the bulk space. A comparison with the weak coupling system, the Pauli paramagnetic susceptibility, is also discussed.
