在这篇文章中，我们使用具有破动不变性的全息模型研究了磁场对输运的影响。我们表明，在仔细减去非平凡磁化电流之后，可以用黑洞视界的性质来表示边界理论的直流输运电流。这使我们能够得到电、热电和导热张量的简单解析表达式。我们的结果适用于各向同性和各向异性模型，包括全息q晶格和某些理论，其中轴的线性源打破了平移不变性。
In this note we study the effects of a magnetic field on transport using holographic models with broken translational invariance. We show that, after carefully sub-tracting off non-trivial magnetisation currents, it is possible to express the DC transport currents of the boundary theory in terms of properties of a black hole horizon. This allows us to obtain simple analytic expressions for the electrical, thermoelectric and heat conductivity tensors. Our results apply to both isotropic and anisotropic models, including holographic Q-lattices and to certain theories where translational invariance is broken by linear sources for axions.
