The symmetry breaking is introduced in a two-fold manner: by the next-to-nearest neighbor hopping of electrons and by the charge-bond interaction - the off-diagonal term of the Coulomb potential. Both terms lead to a pronounced asymmetry of the superconducting order parameter. The next-to-nearest neighbor hopping enhances superconductivity for h-doping, while diminishes it for e-doping. The charge-bond interaction alone leads to the opposite effect and, additionally, to the kinetic-energy gain upon condensation in the underdoped regime. With both terms included, with similar amplitudes, the height of the superconducting dome and the critical doping remain in favor of h-doping. The influence of the charge-bond interaction on deviations from symmetry of the shape of the gap at the Fermi surface in the momentum space is briefly discussed."}],"article_number":"085604","department":[{"_id":"MiLe"}],"doi":"10.1088/1361-648X/aa532f","_id":"1163","intvolume":"        29","publisher":"IOP Publishing Ltd.","scopus_import":"1","author":[{"full_name":"Wysokiński, Marcin","first_name":"Marcin","last_name":"Wysokiński"},{"id":"46C405DE-F248-11E8-B48F-1D18A9856A87","first_name":"Jan","full_name":"Kaczmarczyk, Jan","orcid":"0000-0002-1629-3675","last_name":"Kaczmarczyk"}]}
