Density-functional theory of strongly correlated Fermi gases in elongated harmonic traps
Density-functional theory of strongly correlated Fermi gases in elongated harmonic traps
Two-component Fermi gases with tunable repulsive or attractive interactions inside quasi-one-dimensional (Q1D) harmonic wells may soon become the cleanest laboratory realizations of strongly correlated Luttiger and Luther-Emery liquids under confinement. We present a microscopic Kohn-Sham density-functional theory of these systems, with specific attention to a gas on the approach to …
