Extended Hubbard model on a C molecule
Fei Lin, Erik S. Sørensen, Catherine Kallin +1
The electronic correlations on a C molecule, as described by an extended Hubbard Hamiltonian with a nearest neighbor Coulomb interaction of strength , are studied using q…

Strong Correlation Effects in the Fullerene C20
Fei Lin, Erik S. Sørensen, Catherine Kallin +1
The smallest fullerene, dodecahedral C20, is studied using a one band Hubbard model parameterized by U/t. Results are obtained using exact diagonalization of matrices with linear d…
