摘要

The one-dimensional time-independent Green's function G_0 of a quantum simple harmonic oscillator (SHO) system (V_0(x)=mω~2x~2/2) can be obtained by solving the equation directly. It has a compact expression, which gives correct eigenvalues and eigenfunctions easily. The Green's function G with an additional delta-function potential can be obtained readily. The same technics of solving the Green's function G_0 can be used to solve the eigenvalue problem of the SHO with an generic delta-function potential at an arbitrary site, i.e. V_1(x)∝δ(x-a). The Wronskians play an important and interesting role in the above studies. Furthermore, the approach can be easily generalized to solve the quantum system of a SHO with two or more generic delta-function potentials. We give the solutions of the case with two additional delta-functions for illustration.
