The quest for ever colder temperatures has been a major theme of physics for more than a century, leading to such breakthroughs as the discovery of superfluidity and superconductivity, and more recently the development of laser cooling techniques.

Pitaevsky developed a phenomenological theory of superfluidity of matter (the <<Ginzburg-Pitaevsky theory>>) [1, 32], Investigations in the physics of superfluid liquids allow humanity to penetrate deeper into the complex and often unknown processes occurring in matter at ultralow temperatures in the lowest and orderly energy state of its atoms.
However, these outlines would fail to explain IB's at low spin, where the blocking of the pairing contributions of the odd nucleon is predicted to reduce the nuclear superfluidity, there by increasing the moment of inertia of the odd-A nucleus.
