Generalized η-pairing eigenstates in three-component Hubbard models under a transverse field
F. X. Liu, Z. Song
We investigate three-component Hubbard models on a bipartite lattice in the presence of a trans?verse field. Unlike the two-component Hubbard model, where the η-pairing symmetry su…

Exact interlayer triplet-pairing eigenstates in the extended Hubbard model
F. X. Liu, Z. Song
-pairing symmetry generalizes the pairing mechanisms in superconductivity but is broken in the presence of interlayer interactions. In this work, we extend this approach to trip…
