From frustrated magnetism to spontaneous Chern insulators
H. D. Rosales, F. A. Gómez Albarracín, P. Pujol
We study the behaviour of electrons interacting with a classical magnetic background via a strong Hund coupling. The magnetic background results from a Hamiltonian which favours at…

Degenerate and chiral states in the extended Heisenberg model in the kagome lattice
F. A. Gómez Albarracín, P. Pujol
We present a study of the low temperature phases of the antiferromagnetic extended classical Heisenberg model in the kagome lattice, up to third nearest neighbors. First, we focus…
