Solitary Waves in One-Dimensional Hydrogen-Bonded Systems

抄録

We have studied again the dynamical properties of protons in one-dimensional H-bonded system, taking account of the coupling between the proton motion and the lattice deformation. We find that the solitary waves of the proton-polarization are accompanied by the local lattice-deformations. Kink and antikink solutions correspond to ionic D_t default (H₃O⁺ ion) and L_t default (OH⁻ ion), respectively. Two modes of solitary waves and two modes of phonons are found in the four respective regions of wave velocities.
