Rotational invariance and order-parameter stiffness in frustrated quantum spin systems
L. O. Manuel, A. E. Trumper, H. A. Ceccatto
We compute, within the Schwinger-boson scheme, the Gaussian-fluctuation corrections to the order-parameter stiffness of two frustrated quantum spin systems: the triangular-lattice…
Numerical Study of the Incommensurate Phase in Spin-Peierls Systems
A. E. Feiguin, J. A. Riera, A. Dobry +1
We analyze several properties of the lattice solitons in the incommensurate phase of spin-Peierls systems using exact diagonalization and quantum Monte Carlo. These systems are mod…
Superconductivity and incommensurate spin fluctuations in a generalized t-J model for the cuprates
C. D. Batista, L. O. Manuel, H. A. Ceccatto +1
We consider the slave-fermion Schwinger-boson decomposition of an effective model obtained through a systematic low-energy reduction of the three-band Hubbard Hamiltonian. The mode…
