On Ab Initio Estimations of the Nonlinearity Parameters in the Davydov Model

  • Niels Østergård
Part of the NATO ASI Series book series (NSSB, volume 243)


In the Davydov soliton model of α-helix dynamics discussed in this book the parameters can be obtained from experimental data, but for the nonlinearity parameters (χ’s) these experimental estimates are of a comparatively indirect and uncertain nature. Since some analytic and numeric studies show that soliton propagation in the discrete chain only is possible for | χ| within certain limits it is of interest to look for alternative ways of estimating χ’s.
