Itinerant Ferromagnetism in ultracold Fermi gases
Henning Heiselberg
Itinerant ferromagnetism in cold Fermi gases with repulsive interactions is studied applying the Jastrow-Slater approximation generalized to finite polarization and temperature. Fo…
Crossovers in Unitary Fermi Systems
Henning Heiselberg
Universality and crossover is described for attractive and repulsive interactions where, respectively, the BCS-BEC crossover takes place and a ferromagnetic phase transition is cla…
Induced interactions and superfluidity in optical lattices with multi-component Fermi gases
H. Heiselberg
Many-body effects on superfluidity and transition temperatures are calculated for optical lattices and uniform systems with ultracold multi-component Fermi gases. The induced inter…
Phases in optical lattices vs. Coulomb frustrated HTc cuprates
Henning Heiselberg
Fermionic atoms in 2D optical lattices and electrons in HTc cuprates may both be described by the Hubbard model. However, if Coulomb frustration is responsible for the striped phas…
Phases of Bosons or Fermions in confined optical lattices
H. Heiselberg
Phases of Bose or Fermi atoms in optical lattices confined in harmonic traps are studied within the Thomas-Fermi approximation. Critical radii and particle number for onset of Mott…
Extended Bose-Hubbard model with incompressible states at fractional numbers
H. Heiselberg
The Bose-Hubbard model is extended to include nearest and far neighbor interactions and is related to the fractional quantum Hall effect (FQHE). Both models may be studied in optic…
