In this work, I investigated photo-induced phase transition in strongly-correlated electron systems. Persistent photo-induced insulator to metal transition have been observed in thin films. Photo-induced metal to insulator transition has been achieved in Pr(Ca, Sr)MnO_3 film.

在这项工作中，我研究了强相关电子系统的光诱导相变。在薄膜中观察到持久的光致绝缘体到金属的转变。在Pr(Ca, Sr)MnO_3薄膜中实现了光致金属到绝缘体的转变。
