BEC–BCS Crossover in Strongly Interacting Matter

摘要: A quantum field theoretical approach to the thermodynamics of dense Fermi systems is developed for description formation and dissolution condensates bound states in dependence temperature density. As a model system, we study chiral superconducting phase transitions two-flavor quark matter within NJL their interrelation with quark–antiquark diquark states. The diagram evaluated as function coupling strength, coexistence region symmetry breaking color superconductivity obtained at very strong coupling. crossover between Bose–Einstein condensation resonances (Cooper pairs) continuum discussed Mott effect. This effect consists transition into scattering under influence compression heating. We explain physics transition, special emphasis on role Pauli principle case pion matter.
