  1. 1. Many-body-based DFT treatment of fermions in optical lattices

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Jérémie Westergren; [2017]
    Keywords : DFT; density functional theory; MBA; many-body approximations; Hubbard model; Ultra cold atoms; cold atoms; optical lattice; Physics and Astronomy;

    Abstract : With recent advances in the field of ultra cold atoms one can, by trapping atoms at low temperatures by laser beams, simulate systems which can be adequately described by single-band lattice Hamiltonians. Also, due to the high parameter tunability of the experimental setups, lattice disorder can be introduced in a con- trolled fashion in these systems. READ MORE
