# Nonequilibrium Protocols & Wavefront Engineering
⏎
Engineered time-dependent protocols for controlling nonequilibrium quantum and classical systems — designing a moving "front" (spacetime-dependent quench, or photoexcitation front) that outruns a system's natural signal velocity to achieve a target outcome faster than conventional methods allow. The striking part: the same abstract trick reappears twice, once in quantum many-body state preparation and once in completely unrelated classical nonlinear optics.
