First-order kinetics bottleneck during photoinduced ultrafast insulator-metal transition in 3D orbitally-driven Peierls insulator CuIr${}_2$S${}_4$

M. Naseska, P. Sutar, D. Vengust +5

Ultrafast dynamics across the photoinduced three-dimensional Peierls-like insulator-metal (IM) transition in CuIr${}_2$S${}_4$ was investigated by means of the all-optical ultrafas…
