所以，团队有效利用这种特性制作了毫开尔文到室温的大量程拓扑型温度计，相关设计已得到国家发明专利授权（图4d，专利号：ZL 2022 1 0473035.1）。上述相关成果以“A robust and tunable Luttinger liquid in correlated edge of transition-metal second-order topological insulator TaPdTe”为题发表于《Nature Communica...
One-dimensional (1D) interacting electrons are often described as a Luttinger liquid1,2,3,4 having properties that are intrinsically different from those of Fermi liquids in higher dimensions5,6. In materials systems, 1D electrons exhibit exotic quantum phenomena that can be tuned by both intra-...

We propose a three-terminal spin-polarized STM setup for probing the helical nature of the Luttinger liquid edge state that appears in the quantum spin Hall system. We show that the three-terminal tunneling conductance depends on the angle (θ) between the magnetization direction of the tip and...

我当时也用ED算过这个1D Hubbard model,(最后是用DMRG),可以得到这篇文章一样的结果,尤其是intermidate区域电子会倾向形成一些dimer(对应这里的Fig.2(b)),我们认为是一种spin-incoherent luttinger liquid。不过这个计算,如果只看2kF到4kF crossover,之前似乎有很多人算过类似的了,比如das sarma他们的ED,感觉...
By utilizing the accessibility of this monolayer-substrate system on atomic length scales by scanning tunneling microscopy/spectroscopy (STM/STS) we observe metallic edge channels which display 1D electronic correlation effects. Specifically, we prove the correspondence with a Tomonaga-Luttinger liquid (...
Tomonaga-Luttinger liquidMBESTMConfining interacting particles in one-dimension (1D) changes the electronic behavior of the system fundamentally, which has been studied extensively in the past. Examples of 1D metallic systems include carbon nanotubes, quasi-1D organic conductors, metal chains and domain...
