I will consider a generalization of the Abelian Higgs model in 2+1 dimensions. The model describes a scalar field interacting with a U(1) gauge field and gives rise to vortex solutions carrying magnetic flux. In 3+1 dimensions, the vortex becomes a one-dimensional topological defect which appears in condensed matter physics as a vortex line in type-II superconductors. For a strong magnetic...

The average-density approximation (ADA) is used to construct a nonlocal kinetic energy functional for an inhomogeneous two-dimensional Fermi gas. This functional is then used to formulate a Thomas- Fermi von Weizsa ¨cker-like theory for the description of the ground state properties of the system. The quality of the kinetic energy functional is tested by performing a fully self-consistent...
