论文摘要
在中性$^3 $ HE中探索的费米 - 液体现象学的亮点是，在无碰撞状态中，剪切应力繁殖，好像一个人正在处理固体的横向声子。这种$“ $ Transverse Zero Sound $” $的存在要求准粒子质量增强超过关键值。这种传播的剪切应力在强相关的电子系统中也可能存在吗？尽管与伽利略连续体中的中性情况有明显的差异，但我们得出的结论是，横向零声音应该是通用的。我们提出了在这方面应该非常敏感的实验设置：在低温下，Terahertz辐射通过薄板的传输将大大增强，并伴随着巨大的振荡，这反映了光本身的干扰与$“ $” $“ $材料photon $” $在横向的较横向的液体中，是较横向的液体中液体中液体中的较横向表现出来的。
A highlight of Fermi-liquid phenomenology, as explored in neutral $^3$He, is the observation that in the collisionless regime shear stress propagates as if one is dealing with the transverse phonon of a solid. The existence of this $"$transverse zero sound$"$ requires that the quasiparticle mass enhancement exceeds a critical value. Could such a propagating shear stress also exist in strongly correlated electron systems? Despite some noticeable differences with the neutral case in the Galilean continuum, we arrive at the verdict that transverse zero sound should be generic. We present an experimental setup that should be exquisitely sensitive in this regard: the transmission of terahertz radiation through a thin slab of heavy-fermion material will be strongly enhanced at low temperature and accompanied by giant oscillations, which reflect the interference between light itself and the $"$material photon$"$ being the actual manifestation of transverse zero sound in the charged Fermi liquid.
