We suggest a novel trap of trapping a neutral atom with static electric field of four point charges, and discuss the quantum effects of the cold neutral atom in the trap.
用四个点电荷构造一个简单、新颖的静电势阱，并基于含时薛定谔方程和有限差分时间域方法，研究冷原子在该势阱中的量子力学效应。
The object particle means to the microcosmic particle that its static mass is not zero, for example, electron atom molecule and so on.
实物粒子是指静止质量不为零的微观粒子，如电子、原子和分子等。
