Flat-band ferromagnetism in a correlated topological insulator on a honeycomb lattice
Leonardo S. G. Leite, R. L. Doretto
We study the flat-band ferromagnetic phase of a spinfull and time-reversal symmetric Haldane-Hubbard model on a honeycomb lattice within a bosonization formalism for flat-band Z$_2…

Flat-band ferromagnetism and spin waves in the Haldane-Hubbard model
Leonardo S. G. Leite, R. L. Doretto
We study the flat-band ferromagnetic phase of the Haldane-Hubbard model on a honeycomb lattice within a bosonization scheme for flat-band Chern insulators, focusing on the calculat…

Entanglement entropy for the valence bond solid phases of two-dimensional dimerized Heisenberg antiferromagnets
Leonardo S. G. Leite, R. L. Doretto
We calculate the bipartite von Neumann and second Rényi entanglement entropies of the ground states of spin-1/2 dimerized Heisenberg antiferromagnets on a square lattice. Two disti…
