We study a distinct type of non-Fermi liquid where there exists an infinite number of critical bosonic modes instead of finite number of bosonic modes for the conventional ones. We consider itinerant magnets with both conduction electrons and fluctuating magnetic moments in three dimensions. With Dzyaloshinskii–Moriya interaction, the moments fluctuate near a boson surface in the reciprocal space at low energies when the system approaches an ordering transition. The infinite number of critical modes on the boson surface strongly scatter the gapless electrons on the Fermi surface and convert the metallic sector into a non-Fermi liquid. We explain the physical properties of this non-Fermi liquid. On the ordered side, a conventional non-Fermi liquid emerges due to the scattering by the gapless Goldstone mode from the spontaneous breaking of the global rotational symmetry. We discuss the general structure of the phase diagram in the vicinity of the quantum phase transition and clarify various crossover behaviors.

我们研究了一种独特类型的非费米液体，其中存在无限数量的临界玻色子模式，而不是传统玻色子模式的有限数量。我们考虑在三个维度上同时具有传导电子和波动磁矩的流动磁体。对于 Dzyaloshinskii-Moriya 相互作用，当系统接近有序跃迁时，矩在倒易空间中的玻色子表面附近在低能量下波动。玻色子表面的无限数量的临界模式强烈地散射了费米表面上的无带隙电子，并将金属扇区转化为非费米液体。我们解释了这种非费米液体的物理性质。在订购方面，由于全局旋转对称性的自发破坏导致的无间隙戈德斯通模式的散射，出现了传统的非费米液体。我们讨论了量子相变附近相图的一般结构，并阐明了各种交叉行为。
