无限维空间中具有精确束缚态的多参数振子哈密顿量

Multiparametric oscillator Hamiltonians with exact bound states in infinite-dimensional space

Miloslav Znojil

摘要:

中心D维哈密顿量$H = p^2 + a |\vec{r}|^2 + b |\vec{r}|^4 + >... + z |\vec{r}|^{4q+2}$(其中z=1)被认为是在极限$D \to \infty$,其中数值实验最近揭示了一类新的q参数拟精确解在$q \leq 5$ .我们展示了如何将这些“特权”精确束缚态的系统构造扩展到更高的q(这意味着力的形状具有更高的灵活性),代价是缩小波函数的集合(度N限制在前几个非负整数)。当q=4K+3时,我们猜想在所有K处N=3解的封闭公式的有效性.

英文摘要:

Central D-dimensional Hamiltonians $H = p^2 + a |\vec{r}|^2 + b |\vec{r}|^4 + >... + z |\vec{r}|^{4q+2}$ (where z=1) are considered in the limit $D \to \infty$ where numerical experiments revealed recently a new class of q-parametric quasi-exact solutions at $q \leq 5$. We show how a systematic construction of these "privileged" exact bound states may be extended to much higher q (meaning an enhanced flexibility of the shape of the force) at a cost of narrowing the set of wavefunctions (with degree N restricted to the first few non-negative integers). At q=4K+3 we conjecture the validity of a closed formula for the N=3 solutions at all K.
