具有不定有效质量的Schroedinger方程

Schroedinger equations with indefinite effective mass

Miloslav Znojil, Géza Lévai

摘要:

通过简化模型分析了量子(准)粒子具有位置和激发依赖的有效质量概念的一致性。结果表明,即使有效质量m=m(x,E)本身在有限的坐标x和能量E范围内取负值,系统也可能是稳定的。

英文摘要:

The consistency of the concept of quantum (quasi)particles possessing effective mass which is both position- and excitation-dependent is analyzed via simplified models. It is shown that the system may be stable even when the effective mass m=m(x,E) itself acquires negative values in a limited range of coordinates x and energies E.
