Quantum phases of hard-core bosons in a frustrated honeycomb lattice
Christopher N. Varney, Kai Sun, Victor Galitski +1
Using exact diagonalization calculations, we investigate the ground-state phase diagram of the hard-core Bose-Hubbard-Haldane model on the honeycomb lattice. This allows us to prob…

Exotic quantum spin models in spin-orbit-coupled Mott insulators
Juraj Radic, Andrea Di Ciolo, Kai Sun +1
We study cold atoms in an optical lattice with synthetic spin-orbit coupling in the Mott-insulator regime. We calculate the parameters of the corresponding tight-binding model usin…
