Bethe-Ansatz density-functional theory of ultracold repulsive fermions in one-dimensional optical lattices
Gao Xianlong, Marco Polini, M. P. Tosi +3
We present an extensive numerical study of ground-state properties of confined repulsively interacting fermions on one-dimensional optical lattices. Detailed predictions for the at…
Density-functional theory of strongly correlated Fermi gases in elongated harmonic traps
Gao Xianlong, Marco Polini, Reza Asgari +1
Two-component Fermi gases with tunable repulsive or attractive interactions inside quasi-one-dimensional (Q1D) harmonic wells may soon become the cleanest laboratory realizations o…
Low-temperature magnetization of (Ga,Mn)As semiconductors
T. Jungwirth, J. Masek, K. Y. Wang +12
We report on a comprehensive study of the ferromagnetic moment per Mn atom in (Ga,Mn)As ferromagnetic semiconductors. Theoretical discussion is based on microscopic calculations an…
Emergence of atomic-density waves in a trapped Luther-Emery fermion gas
Gao Xianlong, Marco Polini, Mario P. Tosi +2
We present a novel and comprehensive microscopic study of Luther-Emery-paired phases in a strongly interacting atomic Fermi gas inside a parabolic trap and a one-dimensional (1D) o…
Prospects of high temperature ferromagnetism in (Ga,Mn)As semiconductors
T. Jungwirth, K. Y. Wang, J. Masek +11
We report on a comprehensive combined experimental and theoretical study of Curie temperature trends in (Ga,Mn)As ferromagnetic semiconductors. Broad agreement between theoretical…
Fully Frustrated Cold Atoms
Marco Polini, Rosario Fazio, A. H. MacDonald +1
Fully frustrated Josephson Junction arrays (FF-JJA's) exhibit a subtle compound phase transition in which an Ising transition associated with discrete broken translational symmetry…
