计算了在零温下运动的量子粒子在一维紧束缚链上的生存概率的渐近衰变，该链具有随机放置的不可逆强度γ陷阱。存活概率呈现衰减，P(T)∼exp(-1/4)，比与扩散粒子有关的衰减慢。
The asymptotic decay of the survival probability is calculated for a quantum particle moving at zero temperature on a one-dimensional tight-binding chain possessing randomly placed irreversible traps of strength γ. The survival probability exhibits a decay, P (t)∼ exp (-At 1/4), which is slower than that associated with a diffusing particle.
