ALT EDITORS' SUGGESTION Ultrafast modification of coherent phonons during the photoinduced insulator-to-metal phase transition in neodymium nickelate 9 January, 2026 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 NdNiO3. 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.
