Itinerant ferromagnetism in an atom trap
Physical Review B - Condensed Matter and Materials Physics 79:22 (2009)
Abstract:
We propose an experiment to explore the magnetic phase transitions in interacting fermionic Hubbard systems and describe how to obtain the ferromagnetic phase diagram of itinerant-electron systems from these observations. In addition, signatures of ferromagnetic correlations in the observed ground states are found: for large trap radii (trap radius RT >4, in units of coherence length ξ), ground states are topological in nature-a "skyrmion" in two dimension, and a "hedgehog" in three dimension. © 2009 The American Physical Society.Exact Solution for Bulk-Edge Coupling in the Non-Abelian $\nu=5/2$ Quantum Hall Interferometer
