The Davydov soliton: lessons from dimers and N-mers.
Crystallography Department, Birkbeck College,

The Davydov model describes how energy can be transferred along protein
-helices in the form of a vibration excitation of the peptide
groups called amide I. In the Davydov model the amide I vibration
interacts with the phonon modes of the -helix and solitons can
form. An important, and still unanswered question is that of the thermal
lifetime of the Davydov soliton at biological temperatures. A brief summary
of the field will be presented, with particular emphasis on the behaviour
of the system at finite temperature. Results from quantum dynamics at finite
temperature will be shown.
