  1. 1. Near-local density approximation approach to one-dimensional lattice systems

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

    Author : Basheer Joudeh; [2018]
    Keywords : DFT; Hartree; Hartree-Fock; LDA; BALDA; Mean-field; Hubbard; SOFT; Physics and Astronomy;

    Abstract : Describing many-body quantum systems has been an analytically and computationally challenging task since the advent of quantum mechanics. However, in the past 50 years as a result of our technological advancement and the emergence of methods such as density-functional theory (DFT), we have taken crucial steps forward regarding our ability to study and understand large quantum systems.

  3. 2. 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
