Generalized Radial Equations in a Quantum N-Body Problem

Zhong-Qi Ma, Bing Duan, Xiao-Yan Gu

We demonstrate how to separate the rotational degrees of freedom in a quantum N-body problem completely from the internal ones. It is shown that any common eigenfunction of the tot…

Exact solution to the Schrödinger equation for the quantum rigid body

Zhong-Qi Ma

The exact solution to the Schrödinger equation for the rigid body with the given angular momentum and parity is obtained. Since the quantum rigid body can be thought of as the simp…

Exact Solutions to the Schrödinger Equation for the Inverse-Power Potential in Two Dimensions

Shi-Hai Dong, Zhong-Qi Ma

Utilizing an for the eigenfunctions, we arrive at an exact closed form solution to the Schrödinger equation with the inverse-power potential, $V(r)=ar^{-4}+br^{-3}+c…
