B 35, 3651(R) DOI: http://dx.doi.org/10.1103/PhysRevB.35.36510163-1829http://hdl.handle.net/10919/47851By studying the Anderson lattice Hamiltonian with spin-orbit coupling using an auxiliary boson method, we have examined the hard-core repulsive interactions in heavy-fermion materials. As a consequence of the anisotropy of the repulsive interaction, all lower-order partial-wave Cooper pairings in the even-parity channel are strongly impeded.en-USIn Copyrightphysics, condensed matterArticle - Refereedhttp://journals.aps.org/prb/abstract/10.1103/PhysRevB.35.3651https://doi.org/10.1103/PhysRevB.35.3651
