Charge instabilities and topological phases in the extended Hubbard model on the honeycomb lattice with enlarged unit cell
Adolfo G. Grushin, Eduardo V. Castro, Alberto Cortijo +3
We study spontaneous symmetry breaking in a system of spinless fermions in the Honeycomb lattice paying special emphasis to the role of an enlarged unit cell on time reversal symme…

Enhancing the stability of a fractional Chern insulator against competing phases
Adolfo G. Grushin, Titus Neupert, Claudio Chamon +1
We construct a two-band lattice model whose bands can carry the Chern numbers C=0,pm1,pm2. By means of numerical exact diagonalization, we show that the most favorable situation th…
