Mundy, Giulio Cerullo, and Stefano Dal Conte Due to the high interest in the insulator-metal transition (IMT) in rare-earth nickelates for potential applications, a deep understanding of the role of different degrees of freedom is required. Here, the authors perform transient reflectivity measurements to study the photoinduced IMT in NdNiO 3 . They show that the ultrafast reflectivity change is concomitant with the suppression of the coherent phonons of the insulating phase, revealing a strong connection between the electronic changes and rapid lattice modifications across the IMT.
