论文摘要
在量子物质的电子动力学中,电子波函数的浆果曲率在动量空间中提供了人工磁场(AMF),从而导致对传输系数的非平凡贡献。众所周知,在存在电子电子和/或电子 - phonon相互作用的情况下,由于动量空间中的人造电场(AEF),对电子动力学有额外的贡献。在这项工作中,我们在时间反转但破裂的系统中为电子构建流体动力方程,并找到与AEF相关的新型流体动力系数。此外,我们研究了AEF存在的新型线性和非线性转运系数。
In the electron dynamics in quantum matter, the Berry curvature of the electronic wave function provides the artificial magnetic field (AMF) in momentum space, which leads to non-trivial contributions to transport coefficients. It is known that in the presence of electron-electron and/or electron-phonon interactions, there is an extra contribution to the electron dynamics due to the artificial electric field (AEF) in momentum space. In this work, we construct hydrodynamic equations for the electrons in time-reversal invariant but inversion-breaking systems and find the novel hydrodynamic coefficients related to the AEF. Furthermore, we investigate the novel linear and non-linear transport coefficients in presence of the AEF.
