具有磁场的Schroedinger方程的拟分离变量

Quasiseparation of variables in the Schroedinger equation with a magnetic field

F. Charest, C. Hudon, P. Winternitz

摘要:

考虑量子力学中具有矢量势和标量势的二维可积哈密顿系统。与纯标量势的情况相反,运动的二阶积分的存在并不能保证薛定谔方程中的变量分离。我们引入“准分离变量”的概念,并表明,在许多情况下,它使我们能够减少计算的能量谱和波函数的线性代数。

英文摘要:

We consider a two-dimensional integrable Hamiltonian system with a vector and scalar potential in quantum mechanics. Contrary to the case of a pure scalar potential, the existence of a second order integral of motion does not guarantee the separation of variables in the Schroedinger equation. We introduce the concept of "quasiseparation of variables" and show that in many cases it allows us to reduce the calculation of the energy spectrum and wave functions to linear algebra.
