具有两个双（成对）能级简并的形变振子
Deformed Oscillators with Two Double (Pairwise) Degeneracies of Energy Levels
摘要：
提出了一种方案，它允许获得特殊的$q$ -振荡器模型，其特征在于在拥有两个不同对的简并能级。该方法采用双参数变形$q,p$振子模型，通过适当选择$p$和$q$之间的特殊关系进行求解。对于包含两个退化对$E_1=E_2$和$E_3=E_4$的情况，使用了不同版本的二次关系$p=f(q)$。另一方面，利用一个固定的二次关系，我们得到了两对（成对）简并能级的$p$ -振子。
英文摘要：
A scheme is proposed which allows to obtain special $q$-oscillator models whose characteristic feature consists in possessing two differing pairs of degenerate energy levels. The method uses the model of two-parameter deformed $q,p$-oscillators and proceeds via appropriately chosen particular relation between $p$ and $q$. Different versions of quadratic relations $p=f(q)$ are utilized for the case which implies two degenerate pairs $E_1=E_2$ and $E_3=E_4$. On the other hand, using one fixed quadratic relation, we obtain $p$-oscillators with other cases of two pairs of (pairwise) degenerate energy levels.
