Exact first-order density matrix for a d-dimensional harmonically confined Fermi gas at finite temperature
Brandon P. van Zyl
We present an exact closed form expression for the {\em finite temperature} first-order density matrix of a harmonically trapped ideal Fermi gas in any dimension. This constitutes…

Off-diagonal long-range order in a harmonically confined two-dimensional Bose gas
Brandon P. van Zyl
We investigate the presence of off-diagonal long-range order in a harmonically confined two-dimensional Bose gas. In the noninteracting case, an analytical calculation of the the f…

Local-energy density functionals for an N-dimensional electronic system in a magnetic field
B. P. van Zyl
We present a general approach for the construction of the exact local-energy-density functionals for a uniform N-dimensional electronic system in a magnetic field. For arbitrary di…
