外尔修正全息费米子谱

Holographic fermionic spectrum with Weyl correction

Jian-Pin Wu, Baicheng Xu, Guoyang Fu

摘要:

我们研究了具有非费米液体行为的费米能谱。此外,我们还发现费米子谱的峰高和色散关系都随外尔耦合参量$γ$的变化而呈现非线性,这意味着这种非线性可能归因于麦克斯韦场的非线性。该系统的另一个重要性质是,对于含有$γ<0$的全息费米系统,偏离费米液体的程度比含有$γ>0$的全息费米系统的偏离费米液体的程度大。这表明在双边界场论中存在耦合强度的转变。

英文摘要:

We study the ferminoic spectrum with Weyl correction, which exhibits the non-Fermi liquid behavior. Also, we find that both the height of the peak of the fermionic spectrum and the dispersion relation exhibit a nonlinearity with the variety of the Weyl coupling parameter $γ$, which mean that such nonlinearity maybe ascribe to the one of the Maxwell field. Another important property of this system is that for the holographic fermionic system with $γ<0$, the degree of the deviation from Fermi liquid is heavier than that for the one with $γ>0$. It indicates that there is a transition of coupling strength in the dual boundary field theory.
