摘要:
We present simple analytic expressions for the classical energies of previously obtained nonlinear‐standing‐wave and single‐soliton solutions to the sine‐Gordon equation for a finite‐length system with fixed‐ and free‐boundary conditions. Plots of these energies are presented for several system lengths and the energy expressions are shown to reduce to those appropriate to familiar solutions in the infinite system as the length approaches infinity.
