State. Comm. 165, 33 (2013). The Hamiltonian has been implemented on a square lattice with antiferromagnetic interactions between nearest- and next-nearest neighbors. The nearest-neighbor couplings have different strengths, namely, $J_{1}$ and $J_{1}^{'}$, for the x and y directions, respectively. These couplings compete with the next-nearest ones denoted by $J_{2}$. We obtained a new phase dia","authors_text":"Jose Ricardo de Sousa, Kevin J. Urcia Vidarte, Luigui A. Chero Nunura, Octavio D.
