Competing exotic quantum phases of spin- ultra-cold lattice bosons with extended spin interactions
Chia-Chen Chang, Valéry G. Rousseau, Richard T. Scalettar +1
Advances in pure optical trapping techniques now allow the creation of degenerate Bose gases with internal degrees of freedom. Systems such as Rb, K or Na…
Discriminating antiferromagnetic signatures in ultracold fermions by tunable geometric frustration
Chia-Chen Chang, Richard T. Scalettar, Elena V. Gorelik +1
Recently, it has become possible to tune optical lattices continuously between square and triangular geometries. We compute thermodynamics and spin correlations in the correspondin…
Itinerant ferromagnetism in a Fermi gas with contact interaction: Magnetic properties in a dilute Hubbard model
Chia-Chen Chang, Shiwei Zhang, David M. Ceperley
Ground state properties of the repulsive Hubbard model on a cubic lattice are investigated by means of the auxiliary-field quantum Monte Carlo method. We focus on low-density syste…
