Aspects of sine-Gordon solitons, defects and gates
E Corrigan, C Zambon · Journal of Physics A Mathematical and General · 2004
It was recently noted how the classical sine-Gordon theory can support discontinuities, or 'defects', and yet maintain integrability by preserving sufficiently many conservation laws. Since soliton number is not preserved by a defect, a possible application to the construction of logical gates is suggested.
