Efficient calculation of real-space lattice propagators in the presence of a Fermi sea
Oliver Tong, Mona Berciu
We present an efficient method for computing the real-space propagators (lattice Green's functions) of any tight-binding Hamiltonian in the presence of a Fermi sea with carrier con…

Extended Hubbard Model realized in 2D clusters of molecular anions
Oliver Tong, Katherine A. Cochrane, Bingkai Yuan +3
The Hubbard model, despite its simplicity, is remarkably successful at describing numerous many-body phenomena. However, due to the small class of problems which can be solved exac…
