Abstract One of the main challenges in ultrafast material science is to trigger phase transitions with short pulses light. Here we show how strain waves, launched by electronic and structural precursor phenomena, determine a coherent macroscopic transformation pathway for semiconducting-to-metal transition bistable Ti 3 O 5 nanocrystals. Employing femtosecond powder X-ray diffraction, measure lattice deformation as function time. We monitor early intra-cell distortion around light absorbing...
