Ultrafast isothermal laser treatment shortens phase transition probing time by three orders of magnitude.
Whether amorphous phases show a clear solid-liquid transition is a crucial 21st-century scientific question.
Theoretical model extracts T0—the boundary between amorphous liquid and solid for most materials.
