title = "Soliton stability in a generalized sine-Gordon potential",
abstract = "We study stability of a generalized sine-Gordon model with two coupled scalar fields in two dimensions. Topological soliton solutions are found from the first-order equations that solve the equations of motion. The perturbation equations can be cast in terms of a Schr{\"o}dinger-like operators for fluctuations and their spectra are calculated.",
