一类N维奇异位势的特征值界

Eigenvalue bounds for a class of singular potentials in N dimensions

Richard L. Hall, Nasser Saad

摘要:

本文将早先[J. Phys. A:Math. Gen. 31(1998)963]中关于V(x)= g(x^2)+ f(1/x^2)型光滑变换的特征值界推广到N维情形。特别地,导出了一个简单的公式,它限定了尖峰谐振子势V(x)= x^2 + lambda/x^alpha,alpha > 0,lambda > 0的本征值,并且对所有离散本征值、任意角动量ell和空间维数N都有效。

英文摘要:

The eigenvalue bounds obtained earlier [J. Phys. A: Math. Gen. 31 (1998) 963] for smooth transformations of the form V(x) = g(x^2) + f(1/x^2) are extended to N-dimensions. In particular a simple formula is derived which bounds the eigenvalues for the spiked harmonic oscillator potential V(x) = x^2 + lambda/x^alpha, alpha > 0, lambda > 0, and is valid for all discrete eigenvalues, arbitrary angular momentum ell, and spatial dimension N.
