Description:
Author(s): B. Dalla Piazza, M. Mourigal, M. Guarise, H. Berger, T. Schmitt, K. J. Zhou, M. Grioni, and H. M. Rønnow Using low-energy projection of the one-band t - t ′ - t ′′ Hubbard model we derive an effective spin Hamiltonian and its spin-wave expansion to order 1/ S . We fit the spin-wave dispersion of several parent compounds to the high-temperature superconducting cuprates La 2 CuO 4 , Sr 2 CuO 2 Cl 2 , and Bi 2 Sr 2 YCu 2 O 8 . Our... [Phys. Rev.
