Cooper pairing of fermions is a profound phenomenon that has turn into extremely important in lots of various parts of physics within the fresh prior. This booklet brings jointly, for the 1st time, specialists from numerous fields concerning Cooper pairing, on the point of BCS idea and past, together with the research of novel states of subject reminiscent of ultracold atomic gases, nuclear platforms on the severe, and quark topic with software to neutron stars. Cross-disciplinary in nature, the ebook may be of curiosity to physicists in lots of diversified specialties, together with condensed topic, nuclear, high-energy, and astrophysics. The emphasis is on novel concerns past traditional BCS thought reminiscent of pairing in uneven platforms, the polarization influence, and better spin pairing. those themes are infrequently taken care of on the textbook point and them all are the themes of extensive ongoing learn. The e-book additionally considers numerous new suggestions regularly occurring in present examine that fluctuate considerably from the normal condensed topic methods defined within the average literature.
