Many quantum (and other crystalline) phase transitions involve collective changes in the lattice parameters. We have developed a method for non-destructive generation of large-amplitude acoustic waves [5] that can be used to drive phase transitions by themselves or in conjunction with THz or optical excitation. The combination of multimodal excitation and control with probing from THz to x-ray spectral ranges and with real-time single-shot measurements can seem like a gilded age for fundamental study and potential practical applications of collective dynamics.
