Breaking Peierls theorem in polyacetylene chains via topological design
Xinnan Peng, Marco Lozano, Jie Su +11
Peierls theorem postulates that a one-dimensional (1D) metallic chain must undergo a metal-to-insulator transition via lattice distortion, resulting in bond length alternation (BLA…

1D flat bands in phosphorene nanoribbons with pentagonal nature
Shuo Sun, Jing-Yang You, Zhihao Cai +16
Materials with flat bands can serve as a promising platform to investigate strongly interacting phenomena. However, experimental realization of ideal flat bands is mostly limited t…
