核和夸克-胶子等离子体中的无规性

Randomness in nuclei and in the quark-gluon plasma

A. De Pace, A. Molinari

摘要:

平均随机性的问题主要在核物理中得到解决,但不久也在QCD中得到解决。在处理原子核的连续谱(“光学模型”)方面非常成功的Feshbach方法也被扩展到包括束缚态(“壳模型”)。它与随机矩阵理论的关系进行了讨论,后者对QCD的轴承,特别是在连接的狄拉克算子的频谱,简要地触及。最后,讨论了Feshbach理论是否能满足QCD所要求的平均化问题。

英文摘要:

The issue of averaging randomness is addressed, mostly in nuclear physics, but shortly also in QCD. The Feshbach approach, so successful in dealing with the continuum spectrum of the atomic nuclei ("optical model"), is extended to encompass bound states as well ("shell model"). Its relationship with the random-matrix theory is discussed and the bearing of the latter on QCD, especially in connection with the spectrum of the Dirac operator, is briefly touched upon. Finally the question of whether Feshbach's theory can cope with the averaging required by QCD is considered.
