摘要：We review a new formalism for treating quantum solitons which is much simpler than alternatives such as collective coordinates and less computationally intensive than Hamiltonian truncation. It is particularly simple in the one-soliton sector. We review the formalism and we use it to compute the leading amplitudes and probabilities for inelastic and elastic kink-meson scattering. In particular, we find a peak in the elastic scattering amplitude corresponding to the excitation of the resonance corresponding to the unstable twice-excited shape mode.
