First-order rhombohedral to cubic phase transition in photoexcited GeTe
Matteo Furci, Giovanni Marini, Matteo Calandra
Photoexcited GeTe undergoes a non-thermal phase transition from a rhombohedral to a rocksalt crystalline phase. The microscopic mechanism and the nature of the transition are uncle…

Light-Induced Nonthermal Phase Transition to the Topological Crystalline Insulator State in SnSe
Stefano Mocatti, Giovanni Marini, Matteo Calandra
Femtosecond pulses have been used to reveal hidden broken symmetry states and induce transitions to metastable states. However, these states are mostly transient and disappear afte…
