Long-range donor-acceptor electron transport mediated by alpha-helices
Larissa S. Brizhik, Jingxi Luo, Bernard M. A. G. Piette +1
We study the long-range electron and energy transfer mediated by a polaron on an -helix polypeptide chain coupled to donor and acceptor molecules at opposite ends of the chain.…
Directed polaron propagation in linear polypeptides induced by intramolecular vibrations and external electric pulses
Jingxi Luo, Bernard M. A. G. Piette
We study the propagation of -helix polarons in a model describing the non-adiabatic interaction between an electron and a lattice of quantum mechanical oscillators at physiologi…
Bio-Polymer Hairpin Loops Sustained by Polarons
B. Chakrabarti, B. Piette, W. J. Zakrzewski
We show that polarons can sustain loop-like configurations in flexible bio-polymers and that the size of the loops depend on both the flexural rigidity of the polymer and the elect…
Spontaneous Polaron Transport in Biopolymers
B. Chakrabarti, B. M. A. G. Piette, W. J. Zakrzewski
Polarons, introduced by Davydov to explain energy transport in -helices, correspond to electrons localised on a few lattice sites because of their interaction with phonons. Whil…
Skyrmion Vibration Modes within the Rational Map Ansatz
W. T. Lin, B. Piette
We study the vibration modes of the Skyrme model within the rational map ansatz. We show that the vibrations of the radial profiles and the rational maps are decoupled and we consi…
Scattering of sine-Gordon Breathers on Potential Wells
B. Piette, W. J. Zakrzewski
We analyse the scattering of sine-Gordon breathers on a square potential well. We show that the scattering process depends not only on the vibration frequency of the breather and i…
