摘要:

采用点正则变换(PCT)求解了具有位置依赖有效质量(PDEM)函数的D维薛定谔方程,求解了两种分子赝谐势和修正Kratzer(Mie型)势.通过适当的变换,将变换后的精确可解的D维常质量$D\geq 2$薛定谔方程映射到有效质量方程中,得到了包含能量本征值和相应波函数的精确束缚态解.各种维度的著名的伪谐波和修改Kratzer精确本征态的表现。

英文摘要:

We employ the point canonical transformation (PCT) to solve the D-dimensional Schrödinger equation with position-dependent effective mass (PDEM) function for two molecular pseudoharmonic and modified Kratzer (Mie-type) potentials. In mapping the transformed exactly solvable D-dimensional ($D\geq 2$) Schrödinger equation with constant mass into the effective mass equation by employing a proper transformation, the exact bound state solutions including the energy eigenvalues and corresponding wave functions are derived. The well-known pseudoharmonic and modified Kratzer exact eigenstates of various dimensionality is manifested.
