Magnetization plateaus and sublattice ordering in easy axis Kagome lattice antiferromagnets
Arnab Sen, Kedar Damle, Ashvin Vishwanath
We study kagome lattice antiferromagnets where the effects of easy axis single-ion anisotropy () dominates over the Heisenberg exchange . For , virtual quantum flu…

Superfluid Insulator Transitions of Hard-Core Bosons on the Checkerboard Lattice
Arnab Sen, Kedar Damle, T. Senthil
We study hard-core bosons on the checkerboard lattice with nearest neighbour unfrustrated hopping and `tetrahedral' plaquette charging energy . Analytical arguments and Quan…
