摘要:
我们探索了在无 disorder 的情况下,可压缩但 DC conductivity 消失的 quantum liquids 的可能性。我们证明了从 generic Chern band 中的强相互作用涌现出的 composite Fermi liquid 具有 zero Drude weight,这与 normal Fermi liquids 形成鲜明对比。我们的工作确立了 Drude weight 的缺失作为 composite Fermi liquid phase 的定义性质,这将其与 Fermi liquid 或其他类型的 non-Fermi liquids 区分开来。我们的发现指向了一类可能很广泛的、具有意想不到的 transport 和 optical properties 的 gapless quantum phases。
英文摘要:
We explore the possibility of quantum liquids that are compressible but have vanishing DC conductivity in the absence of disorder. We show that the composite Fermi liquid emerging from strong interaction in a generic Chern band has zero Drude weight, in stark contrast to normal Fermi liquids. Our work establishes the absence of Drude weight as the defining property of the composite Fermi liquid phase, which distinguishes it from the Fermi liquid or other types of non-Fermi liquids. Our findings point to a possibly wide class of gapless quantum phases with unexpected transport and optical properties.
