Fröhlich's condensation in a biological membrane viewed as a Davydov soliton

  • H. Bolterauer
  • J. A. Tuszyński


A model Hamiltonian is postulated for a biological membrane involving phospholipid tails and heads accounting for the presence of dielectrically-active material. It is subsequently demonstrated that under specific conditions, Bose condensation of dipolar oscillations of the head groups may take place in support of Fröhlich's earlier conjecture. A new effect is found here that this condensation phenomenon can be interpreted as the emergence of a Davydov soliton in the momentum space for dipole oscillations.
