Variational approximations to breather modes in the discrete sine-Gordon equation

Abstract Long-lived breather-like modes have been observed in the numerical simulations of discrete sine-Gordon systems. However, little analytical work has been carried out on these systems. We show how to use the Variational form of nonlinear Klein-Gordon equations to find corrections to breather modes caused by discreteness.
