超对称量子力学

Supersymmetric Quantum Mechanics

David J. Fernandez C

摘要:

超对称量子力学(SUSY QM)是一个强有力的工具,可以用来产生新的势能,而这些新的势能的谱是已知的。在这些课堂讲稿中,我们将给出关于一维任意系统的一阶和二阶超对称量子力学的一些一般公式,并将通过三角Poschl-Teller势来说明该方法。一些内在相关的主题,如新的哈密顿量继承的代数结构和相应的相干态将被分析。该技术也将实施周期性的潜力,相应的频谱是由允许的带分开的能隙。

英文摘要:

Supersymmetric quantum mechanics (SUSY QM) is a powerful tool for generating new potentials with known spectra departing from an initial solvable one. In these lecture notes we will present some general formulas concerning SUSY QM of first and second order for one-dimensional arbitrary systems, and we will illustrate the method through the trigonometric Poschl-Teller potentials. Some intrinsically related subjects, as the algebraic structure inherited by the new Hamiltonians and the corresponding coherent states will be analyzed. The technique will be as well implemented for periodic potentials, for which the corresponding spectrum is composed of allowed bands separated by energy gaps.
