暗光子存在下的手征动力学理论

Chiral kinetic theory in the presence of dark photon

Marek Rogatko, Karol I. Wysokinski

摘要:

在固体的传输特性中发现暗物质的特征将是探测我们宇宙质量中这种虚幻成分的重要一步。这是特别重要和及时的,因为旨在直接探测暗物质粒子的实验继续提供负面结果。作为在这个方向上的第一步,我们考虑拓扑非平凡的Weyl或Dirac半金属,并推导出修改后的动力学方程,考虑到两个耦合的$U(1)$ -规范场,一个是标准的麦克斯韦电磁场和其他相应的黑暗部门。由此产生的玻尔兹曼动力学方程修改的Berry曲率耦合到可见和黑暗的扇区规范场。结果表明,由于规范场与暗扇区磁场之间的耦合常数的出现,暗扇区引起输运系数的改变。

英文摘要:

Finding signatures of dark matter in transport characteristics of solids would be an important step on the road to detect this illusive component of the mass of our Universe. This is especially important and timely as the experiments designed to directly detect dark matter particles continue to provide negative results. As a first step in this direction we consider topologically non-trivial Weyl or Dirac semimetals and derive the modified kinetic equation taking into account two coupled $U(1)$-gauge fields, one being the standard Maxwell electromagnetic field and other corresponding to the dark sector. The resulting Boltzmann kinetic equation is modified by the Berry curvature which couples to both visible and dark sector gauge fields. It was revealed that the dark sector induces modifications of transport coefficients due to the appearance of coupling constant between gauge fields and dark sector magnetic field.
