The microscopic spin-phonon coupling constants in CuGeO_3
R. Werner, C. Gros, M. Braden
Using RPA results, mean field theory, and refined data for the polarization vectors we determine the coupling constants of the four Peierls-active phonon modes to the spin chains o…

Dynamics of the Peierls-active phonon modes in CuGeO_3
Claudius Gros, Ralph Werner
We reconsider the Cross and Fischer approach to spin-Peierls transitions. We show that a soft phonon occurs only if Omega_0<2.2 T_SP. For CuGeO_3 this condition is not fulfilled an…
