论文摘要
对谐振 - 元素系统的奇异分数Fermi-liquid fl $^*$理论结合了谐振 - 价值键（RVB）状态和当前载体的带。该理论的应用在使用各种骨气和费米子表示中提出了自旋液体，抗磁性和几乎抗铁磁系统，这与正在执行的$ s-d（f）$交换模型中的扰动理论进行了比较。处理包括小费米表面的形成在内的拓扑方面。在狭窄的频带（强相关）的情况下，基态被认为是RVB和Dopon或Weng的Fermion状态的直接乘积。讨论了Kondo Lattices，掺杂的Pyrochlores和Metallic $β$ -MN，YMN $ _2 $，Y $ _ {1-x} $ SC $ _X $ _X $ MN $ _2 $系统，类似物与铜系统进行处理。
An exotic fractionalized Fermi-liquid FL$^*$ theory of metallic systems, which combines resonant-valence-bond (RVB) state and the band of current carriers, is treated. An application of this theory to spin-liquid, antiferromagnetic and nearly antiferromagnetic systems is proposed with the use of various bosonic and fermionic representations, a comparison with perturbation theory in the $s-d(f)$ exchange model being performed. The topological aspects including formation of the small Fermi surface are treated. In the case of narrow bands (strong correlations), the ground state is considered as a direct product of RVB and dopon or Weng's fermion states. Examples of Kondo lattices, doped pyrochlores, and metallic $β$-Mn, YMn$_2$, Y$_{1-x}$Sc$_x$Mn$_2$ systems are discussed, analogies with copper-oxide systems being treated.
