Ferromagnetic response of a "high-temperature" quantum antiferromagnet
Xin Wang, Rajdeep Sensarma, Sankar Das Sarma
We study the finite temperature antiferromagnetic phase of the ionic Hubbard model in the strongly interacting limit using quantum Monte Carlo based dynamical mean field theory. We…

Mott insulating phases and magnetism of fermions in a double-well optical lattice
Xin Wang, Qi Zhou, S. Das Sarma
We theoretically investigate, using non-perturbative strong correlation techniques, Mott insulating phases and magnetic ordering of two-component fermions in a two-dimensional doub…
