In article number 2003832 by Jian Zhou, Ju Li, and co-workers, optomechanical theory is derived and applied to predict terahertz optics driven ultrafast and reversible topological phase transitions in transition metal dichalcogenide monolayers, which is a damage-free and non-contacting approach that compensates other strategies. The cover displays such a novel optical strategy to trigger a thermal topological phase transition.

拓扑相变：单层过渡金属二硫属化物的太赫兹驱动可逆拓扑相变（Adv. Sci. 12/2021）

在Jian Zhou、Ju Li 和同事的文章编号2003832 中，推导并应用光机械理论来预测过渡金属二硫属化物单层中太赫兹光学驱动的超快和可逆拓扑相变，这是一种无损伤和非接触的方法这补偿了其他策略。封面展示了这种新颖的光学策略来触发热拓扑相变。
