Abstract
Phonon emission from a large-amplitude discrete sine-Gordon breather was studied numerically for a small degree of discreteness. In contrast to the case of highly discrete system investigated by Boesch and Peyrard (Phys. Rev. B 43 (1991) 8491), it was found that the resonance between the breatherʹs oscillation and the phonons of the lower phonon band edge (κ=0) takes place for a small degree of discreteness.
