A nonlocal kinetic energy functional for an inhomogeneous two-dimensional Fermi gas
B. P. van Zyl, A. Farrell, E. Zaremba +3
The average-density approximation is used to construct a nonlocal kinetic energy functional for an inhomogeneous two-dimensional Fermi gas. This functional is then used to formulat…
Thomas-Fermi von Weizsäcker theory for a harmonically trapped, two-dimensional, spin-polarized dipolar Fermi gas
Brandon P. van Zyl, E. Zaremba, P. Pisarski
We systematically develop a density functional description for the equilibrium properties of a two-dimensional, harmonically trapped, spin-polarized dipolar Fermi gas based on the…
Multi-site mean-field theory for cold bosonic atoms in optical lattices
T. McIntosh, P. Pisarski, R. J. Gooding +1
We present a detailed derivation of a multi-site mean-field theory (MSMFT) used to describe the Mott-insulator to superfluid transition of bosonic atoms in optical lattices. The ap…
Application of a multi-site mean-field theory to the disordered Bose-Hubbard model
P. Pisarski, R. M. Jones, R. J. Gooding
We present a multi-site formulation of mean-field theory applied to the disordered Bose-Hubbard model. In this approach the lattice is partitioned into clusters, each isolated clus…
Analyzing the success of T-matrix diagrammatic theories in representing a modified Hubbard model
P. Pisarski, R. J. Gooding
We present a systematic study of various forms of renormalization that can be applied in the calculation of the self-energy of the Hubbard model within the T-matrix approximation.…
Local density of states induced by anisotropic impurity scattering in a d-wave superconductor
P. Pisarski, G. Haran
We study a single impurity effect on the local density of states in a d-wave superconductor accounting for the momentum-dependent impurity potential. We show that the anisotropy of…
Effect of anisotropic impurity scattering on a density of states of a d-wave superconductor
A. Maciag, P. Pisarski, G. Haran
We discuss the effect of an anisotropic impurity potential on the critical temperature, local density of states in the vicinity of a single impurity, and the quasiparticle density…
