Abstract:
We analytically describe solitons and spin waves in the helicoidal structure
of magnets without an inversion center using the “dressing” method in the framework of the sine-Gordon model. Analyzing the nonlinear dynamics of spin
waves in the helicoidal-structure background reduces to solving linear integral
equations on a Riemann surface generated by the superstructure. We obtain
spectral expansions of integrals of motion with the soliton and spin-wave
contributions separated.
Keywords:
helicoidal structure, sine-Gordon equation, Riemann problem, kink, breather.
