摘要
利用具有二维周期性的类抛物晶格势,研究了轻原子在金属晶体中的量子行为.结果表明:体系的对称性主导粒子的局域态;非简谐振动项导致高激发态的劈裂和偶然简并;降低势阱的对称性能使劈裂加剧;处于基态和低激发态的原子以较高概率分布于阱底附近区域,进行局域振动.
The quantum states of light elements in 2-dimensional anharmonic lattice potential are calculated by solving Schroedinger equation. The result shows that the degeneracy of energy level is dominated mainly by the cell symmetry and slightly affected by the anharmonicy. The anharmonic potential causes accidental splitting and degeneracy to rome excited states, while the lowering of symmetry enhances the splitting of all degenerate levels, but makes the anharmonic effect less obvious.
