自发生成晶格中的全息费米液体

Holographic Fermi Liquids in a Spontaneously Generated Lattice

James Alsup, Eleftherios Papantonopoulos, George Siopsis, Kubra Yeter

摘要:

我们讨论费米子在一个自发产生的全息晶格背景。边界处的晶格结构是通过在U(1)规范场和标量场之间引入一个高导数相互作用项而产生的。我们解决了低于临界温度的晶格形成的运动方程,并分析了由于晶格费米面的变化。费米子能带结构被发现表现出由于晶格效应的带隙。

英文摘要:

We discuss fermions in a spontaneously generated holographic lattice background. The lattice structure at the boundary is generated by introducing a higher-derivative interaction term between a U(1) gauge field and a scalar field. We solve the equations of motion below the critical temperature at which the lattice forms, and analyze the change in the Fermi surface due to the lattice. The fermion band structure is found to exhibit a band gap due to lattice effects.
