Stability of homogeneous magnetic phases in a generalized t-J model
L. O. Manuel, H. A. Ceccatto
We study the stability of homogeneous magnetic phases in a generalized t-J model including a same-sublattice hopping t' and nearest-neighbor repulsion V by means of the slave fermi…

Magnetic and quantum disordered phases in triangular-lattice Heisenberg antiferromagnets
L. O. Manuel, H. A. Ceccatto
We study, within the Schwinger-boson approach, the ground-state structure of two Heisenberg antiferromagnets on the triangular lattice: the J1-J2 model, which includes a next-neare…
