Microscopic approach to exotic superconductivity in f-electron systems

Abstract Based on a multi-orbital Hubbard model constructed from the j – j coupling scheme, we discuss microscopic aspects of f-electron triplet pairing in the ferromagnetic phase. From some numerical results both for square and honeycomb lattices, it is suggested that the appearance of odd-parity triplet pairing induced by Hund's rule interaction should depend on the inversion symmetry of the lattice.
