标题： Weyl Geometry in Weyl Semimetals

摘要： 在存在空位的外尔半金属中，最近发现直流电导率出现了一种新的振荡行为，这种行为发生在没有外部磁场的情况下。 在这里，我们认为这种效应可以从几何角度解释为由涌现的外尔连接引起的类似磁场。 这种几何规范场与底层有效几何的非度规性有关，而非度规性是由晶格系统中的空位物理诱导产生的。 最后，我们假设外尔半金属中的手征磁效应可能受到动态空位存在的影响。 显示英文摘要

摘要： A novel oscillatory behaviour of the DC conductivity in Weyl semimetals with vacancies has recently been identified, occurring in the absence of external magnetic fields. Here, we argue that this effect has a geometric interpretation in terms of a magnetic-like field induced by an emergent Weyl connection. This geometric gauge field is related to the non-metricity of the underlying effective geometry, which is physically induced by vacancies in the lattice system. Finally, we postulate that the chiral magnetic effect in Weyl semimetals can be affected by the presence of dynamical vacancies.
