Topological metals constructed by sliding quantum wire arrays

Autor: Zheng-Wei Zuo, Linxi Lv, Dawei Kang

Publikováno v: Physical Review B. 107

A general strategy of alternated slide construction to craft topological metals is proposed, where there is a relative slide between the odd and even chains in the trivial spinless quantum wire array. Firstly, taking the three-leg ladder as an exampl

The effect of spatially modulated interaction on quantum phase transition in one-dimensional interacting spinless fermion system is theoretically investigated by exact diagonalization and density matrix renormalization group method. Our calculations

Tuning the interlayer twist angle provides a new degree of freedom to exploit the potentially excellent properties of two dimensional layered materials. Here we investigate the structural and electronic properties of twisted bilayer SiC under a serie

The nature of the state at low Landau-level filling factors has been a longstanding puzzle in the field of the fractional quantum Hall effect. While theoretical calculations suggest that a crystal is favored at filling factors $\nu\lesssim 1/6$, expe

Publikováno v: Applied Physics Letters. 119:192408

Nanographene exhibits manifold magnetic orders depending on its topology. The Clar's goblet, envisioned 50 years ago and synthesized recently, is an emblematic nanographene with an antiferromagnetic ground state induced by topological frustration. In
