Description
Triangular graphene quantum dots (TGQD) with zig-zag edges are synthetic structures in which the presence of a zero-energy shell at the Fermi level generates electronic correlations and entanglement. We present here the result of Hubbard model calculations in TGQD and show the spin-polarized energy spectrum for spin up and down. We also calculate the density matrix elements for bilayer bulk graphene analytically and numerically from the tight-binding (TB) Hamiltonian. Lastly, we calculate Coulomb matrix elements for a TGQD with 13 atoms.
