摘要: 先通过运用量子动力学代数的方法引入升降算符解决了量子力学的一维空间中的第二类Poschl—Teller势能体系定态问题,然后利用这对升降算符构造一个与体系相关的SU(2)代数,进一步讨论第二类Poschl—Teller势能体系定态的本征值.

Abstract: A quantum dynamical algebraic approach is proposed, which is associated with a pair of the raising and lowering opera- tors for solving the bound energy eigen-problem for one-dimensional quantum system with the second Poschl-Teller potential. In addi- tion, the SU(2) Lie algebra related to this quantum system can be built naturally based on the Hamilton operator as well as the raising and lowering operators. The eigen-values and eigen-functions of a physical system in the potential of this kind are also obtained by u- sing the present algebraic technique.
Key words: quantum dynamics, raising and lowering operators, the second Poschl-Teller potential system, SU(2) Lie algebra
