S. Sree Ranjani, A. K. Kapoor, P. K. Panigrahi

摘要:

各种准精确的可解性条件,涉及的参数的周期性相关的Lam{é}潜力,自然出现在量子Hamilton-Jacobi方法。研究发现,Riccati型量子Hamilton-Jacobi方程的内在非线性是导致Lam{é}情形下大量可解性条件的主要原因.我们还研究了量子动量函数的奇异性结构,从而得到了带边本征值和本征函数。

英文摘要:

Various quasi-exact solvability conditions, involving the parameters of the periodic associated Lam{é} potential, are shown to emerge naturally in the quantum Hamilton-Jacobi approach. It is found that, the intrinsic nonlinearity of the Riccati type quantum Hamilton-Jacobi equation is primarily responsible for the surprisingly large number of allowed solvability conditions in the associated Lam{é} case. We also study the singularity structure of the quantum momentum function, which yields the band edge eigenvalues and eigenfunctions.
