In situ imaging of the dynamics of photo-induced structural phase transition at high pressures by picosecond acoustic interferometry

Picosecond acoustic interferometry is used to monitor in time the motion of the phase transition boundary between two water ice phases, VII and VI, coexisting at a pressure of 2.15 GPa when compressed in a diamond anvil cell at room temperature. By analyzing the time-domain Brillouin scattering sign...
