Using the entropic quantifier called statistical complexity, we investigate the interplay between (1) pairing interactions between fermions, can be viewed as analogous with superconductivity based on Cooper pairs; (2) rotations of the system as a whole around an axis; and (3) thermal excitations. Two different ordering processes are at work: alignment and pairing of two fermions to total spin zero. They compete among themselves and with thermal disorder. A complex physics ensues as a consequence. The existence of novel phenomena is revealed by the behavior of the statistical complexity. In particular, it is seen how order can arise out of disorder in originating high-temperature superconductivity.
利用称为统计复杂性的熵量化器,我们研究了以下三者之间的相互作用:(1)费米子之间的配对相互作用,可视为类似于基于库珀对的超导性;(2)系统整体围绕轴的旋转;以及(3)热激发。两种不同的有序化过程在起作用:两个费米子的排列和配对至总自旋为零。它们相互竞争,并与热无序竞争。结果产生了复杂的物理现象。统计复杂性的行为揭示了新现象的存在。特别是,可以看到在高温超导起源中无序如何产生有序。
