相伴的Lambertman方程、周期势和sl(2,R)

Associated LamÉ Equation, Periodic Potentials and sl(2,R)

Asish Ganguly

摘要:

本文提出了一种新的方法,通过对sl(2,R)中的缔合Lamé方程\[-ψ''(x) + [ m(m+1)k^{2}sn^{2}x + \ell(\ell+1)k^{2}(cn^{2}x/dn^{2}x)]ψ(x) = Eψ(x)\]进行代数化,得到相应的周期势.对于整数m,$\ell$,得到了带边本征函数和能谱.对于半整数m和整数或半整数$\ell$,我们也得到了解的显式表达式.

英文摘要:

We propose a new approach based on the algebraization of the Associated Lamé equation \[-ψ''(x) + [ m(m+1)k^{2}sn^{2}x + \ell(\ell+1)k^{2}(cn^{2}x/dn^{2}x)]ψ(x) = Eψ(x)\] within sl(2,R) to derive the corresponding periodic potentials. The band edge eigenfunctions and energy spectra are explicitly obtained for integers m,$\ell$. We also obtain the explicit expressions of the solutions for half-integer m and integer or half-integer $\ell$.
