Abstract

We investigate dynamics properties of proton transfer in hydrogen-bonded ferroelectrics with asymmetric double-well potential, in an externally applied field, based on a two-component model. We obtain the equations of motion and their soliton solution. The soliton velocity and conductivity are found; this expression shows that the phase-transition critical index is equal to unity, and this value coincides quite well with the experimental result.
