Collective excitation or quasiparticle is the key feature of many-body quantum systems. In spite of the rapid progresses in the field of the collective excitation and its damping in ultracold atom system, most of the trapping potentials studied up to now are based on harmonic trap. In this talk, I introduce a new nonlinear damping mechanism in the lowest-lying excitation, based on continually shaking quantum gases in a uniform box trap. We observe power-scaling for damping rate, and propose a minimal model to elucidate the nonlinear damping behaviour.
