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  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.
