相对论薛定谔理论中的规范不变能量泛函

Gauge-Invariant Energy Functional in Relativistic Schroedinger Theory

M. Mattes, M. Sorg

摘要:

严格考虑相对论薛定谔理论的非阿贝尔性质,改进了前一篇文章中的非不变能量泛函,使其具有规范不变形式.作为结果的一个应用,正电子偶素相对于单重态和三重态的二分法进行了讨论(邻位和对位正电子偶素)。如果(i)磁相互作用被忽略(如在传统理论中)和(ii)电相互作用势的各向异性被忽略,则邻位和对位态的简并发生在π中。鉴于这样一个非常粗略的近似过程,在爱因斯坦的非相对论性正电子偶素谱与传统的预测惊人地一致。

英文摘要:

The non-invariant energy functional of the preceding paper is improved in order to obtain its gauge-invariant form by strictly taking into account the non-Abelian character of Relativistic Schroedinger Theory (RST). As an application of the results, the dichotomy of positronium with respect to singlet and triplet states is discussed (ortho- and para-positronium). The degeneracy of the ortho- and para-states occurs in RST if (i) the magnetic interactions are neglected (as in the conventional theory) and (ii) the anisotropy of the electric interaction potential is disregarded. In view of such a very crude approximation procedure, the non-relativistic positronium spectrum in RST agrees amazingly well with the conventional predictions.
