Fig. 1: Illustrations of QSH-QAH phase transitions within Xenes under the irradiation of CPL.

From: Light-induced above-room-temperature Chern insulators in group-IV Xenes

Fig. 1

a Top view of monolayer Xenes with two opposite chirality of edge states, in which the red and blue square loops with opposite arrows stand for the chiral edge states with positive and negative chirality, respectively. b and c are corresponding to the conditions under the irradiation of R-CPL and L-CPL separately. In each subfigure, the large light-red and light-blue arrows located in the top-left corner stand for the incidence of R-CPL and L-CPL. The gray balls stand for Si, Ge, or Sn atoms.
