论文摘要
利用拓扑Landau Fermi液体和手性动力学理论，在紧张的Weyl半含量中发现了异国情调异常的等离子体模式，其中准粒子相互作用是通过远距离库仑和残留的短距离相互作用来建模的。间隙的集体模式来自散装和表面之间的动态电荷泵，其行为就像$ k _ {\ rm f}^{ - 1} $。电荷振荡由诱导的电场和背景伪场之间的耦合准确确定。这种新颖的模式在伪磁场上分散在单向上，并以明显违反Wiedemann-Franz定律的形式表现出异常的导热性。通过THZ状态中晶格的机械振动，可以通过实验实现激发。
An exotic anomalous plasmon mode is found in strained Weyl semimetals utilizing the topological Landau Fermi liquid and chiral kinetic theories, in which quasiparticle interactions are modeled by long-range Coulomb and residual short-range interactions. The gapped collective mode is derived from the dynamical charge pumping between the bulk and the surface and behaves like $k_{\rm F}^{-1}$. The charge oscillations are accurately determined by the coupling between the induced electric field and the background pseudofields. This novel mode unidirectionally disperses along the pseudomagnetic field and manifests itself in an unusual thermal conductivity in apparent violation of the Wiedemann-Franz law. The excitation can be achieved experimentally by mechanical vibrations of the crystal lattice in the THz regime.
