Observation of Gapped Dirac Cones in a Two-Dimensional Su-Schrieffer-Heeger Lattice
Daiyu Geng, Hui Zhou, Shaosheng Yue +6
The Su-Schrieffer-Heeger (SSH) model in a two-dimensional rectangular lattice features gapless or gapped Dirac cones with topological edge states along specific peripheries. While…

Atomic-scale Manipulation of Single-Polaron in a Two-Dimensional Semiconductor
Huiru Liu, Aolei Wang, Ping Zhang +9
Polaron is a composite quasiparticle derived from an excess carrier trapped by local lattice distortion, and it has been studied extensively for decades both theoretically and expe…
