Cooper pairspseudobosonsOver 20 years ago, one of us suggested the title was affirmative. In 2012, Cooper pairs were identified in several, but not all "aromatic" compounds tested, benzene being one. This manuscript discusses the formation of three time-reversed pairs of states forming pseudo...
while that of a polymer can be as high as several hundred thousand thousands. These big molecules or 'macro-molecules' are made up of much smaller molecules. The small molecules, which combine to form a big molecule, can be of one or more chemical compounds. To illustrate, imagine that a...
