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…

Wigner Crystallization in Two Dimensions: Evolution from Long- to Short-Ranged Forces

Benjamin M. Fregoso, C. A. R. Sá de Melo

We study fermions in two dimensions interacting via a long-ranged 1/r potential for small particle separations and a short-ranged 1/r^3 potential for larger separations in comparis…

Adiabatic continuity between Hofstadter and Chern insulator states

Ying-Hai Wu, J. K. Jain, Kai Sun

We show that the topologically nontrivial bands of Chern insulators are adiabatic cousins of the Landau bands of Hofstadter lattices. We demonstrate adiabatic connection also betwe…

Topological flat band models with arbitrary Chern numbers

Shuo Yang, Zheng-Cheng Gu, Kai Sun +1

We report the theoretical discovery of a systematic scheme to produce topological flat bands (TFBs) with arbitrary Chern numbers. We find that generically a multi-orbital high Cher…

Quantum phases of disordered flatband lattice fractional quantum Hall systems

Shuo Yang, Kai Sun, S. Das Sarma

By numerical exact diagonalization techniques, we obtain the quantum phase diagram of the lattice fractional quantum Hall (FQH) systems in the presence of quenched disorder. By imp…
