荷电膨胀引力中全息费米子的偶极耦合效应

Dipole Coupling Effect of Holographic Fermion in Charged Dilatonic Gravity

Wen-Yu Wen, Shang-Yu Wu

摘要:

本文研究了Gubser和Rocha(arXiv:0911.2898)提出的荷电双电子黑洞中全息费米子的偶极耦合效应.结果表明,在偶极耦合扰动下,费米液体的性质是刚性的,费米动量线性移动。当耦合变得足够大时,动态地产生间隙,并且当体偶极耦合进一步增加时,费米表面不再存在。

英文摘要:

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.
