摘要: A general theoretical framework for the study of electronic stopping particle projectiles in crystalline solids is proposed. It neither relies on perturbative or linear response approximations, nor an ideal metal host. Instead, it exploits discrete translational symmetries a space-time diagonal determined by projectile with constant velocity moving along trajectory periodicity. This allows characterisation (stroboscopically) stationary solutions, means Floquet theory time-periodic systems. Previous and non-linear jellium models are recovered from this theory. An analysis threshold effect insulators presented based quasi-energy conservation.
