Mamedov, T. Ade Llano, M.2024-02-282024-02-2820151557-1939http://hdl.handle.net/11727/11690A weak-coupling scenario wherein bosonic preformed electron pairs emerge upon cooling from two-electron correlations can explain the pseudogap phase consisting of segments where a Bogoliubov-like energy-momentum relation gapped spectrum alternates with a normal ungapped one. Bose-Einstein condensation (BEC) of preformed pairs interacting with the background fermions leads to either d- or s wave-like superconducting gaps, the result being sensitive to the magnitude of the total number density of pairs n (B) at which BEC occurs and becomes possible already for a moderately anisotropic s wave pairing of fermions repelling each other via isotropic coulombic forces. The present model is compatible with the coexistence of both pseudogap and of superconductivity phenomena.enginfo:eu-repo/semantics/closedAccessHIGH-TEMPERATURE SUPERCONDUCTIVITYTRANSITION-TEMPERATURESYMMETRYSTATEMODELGAParticle2822912960003493501000041557-1947
