Instanton gas approach to the Hubbard model
We consider a path integral formulation of the Hubbard model based on a Hubbard-Stratonovich transformation that couples the auxiliary field to the local electronic density.... -
Sublattice modulated superconductivity in the kagome Hubbard model
We identify a superconducting order featuring spatial pair modulations on the kagome lattice subject to on-site Hubbard 𝑈 and nearest-neighbor 𝑉 interactions. Within our... -
