摘要
本文得到了一维无限深方势阱单个粒子对缓慢移动阱壁作用力的解析公式.该结果被推广到势阱中有多个无相互作用费米子的情况。在绝对零度时,多粒子相干力主要来源于最高能量本征态和比它高一级的能量本征态之间的相干效应。
An analytical force formula of a particle exerting on a slowly moving wall of a one-dimensional infinite square-well potential is obtained. This result is extended into the situation of many non-interacting Fermi particles. At absolute zero temperature, the coherent part in the force is mainly contributed by the eigenstates with the highest energy level and its higher next one.
