Inhomogeneous spin diffusion in traps with cold atoms
H. Heiselberg
The spin diffusion and damped oscillations are studied in the collision of two spin polarized clouds of cold atoms with resonant interactions. The strong density dependence of the…

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…
