Two-electron bound state formation in the t-J-U model for exchange-coupled planes
A. Morriss-Andrews, R. J. Gooding
An anisotropic t-J-U model Hamiltonian is used to model electron behaviour in quasi-2d materials in the dilute limit, and as a highly simplified representation of the weakly couple…

Exact diagonalization analysis of the Anderson-Hubbard model and comparison to real-space self-consistent Hartree-Fock solutions
X. Chen, P. W. Leung, R. J. Gooding
We have obtained the exact ground state wave functions of the Anderson-Hubbard model for different electron fillings on a 4x4 lattice with periodic boundary conditions - for 1/2 fi…
