标题： Dipole Coupling Effect of Holographic Fermion in Charged Dilatonic Gravity

摘要： 在这篇短文中，我们研究了由Gubser和Rocha（arXiv:0911.2898）提出的带电标量黑洞中的全息费米子的偶极耦合效应。 结果表明，费米液体的性质在偶极耦合扰动下是刚性的，并且费米动量发生线性偏移。 当耦合变得足够大时，能隙被动态生成，而当整体偶极耦合进一步增加时，费米面停止存在。 显示英文摘要

摘要： In this note, we study the dipole coupling effect of holographic fermion in a charged dilatonic black hole proposed by Gubser and Rocha (arXiv:0911.2898). It is found that the property of Fermi liquid is rigid under perturbation of dipole coupling, and the Fermi momentum is linearly shifted. A gap is dynamically generated as the coupling becomes large enough and the Fermi surface ceases to exist as the bulk dipole coupling further increases.
