通过在具有Lifshitz类IR几何和AdS4边界的膨胀黑膜中施加相对论边界项和违反Lorentz的相对论边界项，我们研究了费米子谱函数的性质。我们发现，在这两个不动点上，都有浮现的费米面结构，并且许多性质似乎与费米液体的性质一致。特别是，低能行为表现出线性色散关系。此外，我们还发现在膨胀黑膜的背景中也出现了全息平带。
By imposing the relativistic boundary term and Lorentz violating that in the dilatonic black brane with a Lifshitz like IR geometry and AdS4boundary, we study the properties of the spectral functions of the fermions. We find that in the two fixed points, there are emergent Fermi-surface structures and many properties seem to be in agreement with that of Fermi liquid. Especially, the low energy behavior exhibits a linear dispersion relation. In addition, we also find that a holographic flat band also emerges in this background of the dilatonic black brane.
