Vibron-polaron in alpha-helices. II. Two-vibron bound states
Cyril Falvo, Vincent Pouthier
The two-vibron dynamics associated to amide-I vibrations in a 3D -helix is described according to a generalized Davydov model. The helix is modeled by three spines of hydrogen-b…
Vibron-polaron in alpha-helices. I. Single-vibron states
Cyril Falvo, Vincent J. C. Pouthier
The vibron dynamics associated to amide-I vibrations in a 3D alpha-helix is described according to a generalized Davydov model. The helix is modeled by three spines of hydrogen-bon…
Relaxation channels of two-vibron bound states in α-helix proteins
Vincent J. C. Pouthier, Cyril Falvo
Relaxation channels for two-vibron bound states in an anharmonic alpha-helix protein are studied. It is pointed out that the relaxation originates in the interaction between the dr…
Two-vibron bound states in alpha-helix proteins : the interplay between the intramolecular anharmonicity and the strong vibron-phonon coupling
Vincent Pouthier
The influence of the intramolecular anharmonicity and the strong vibron-phonon coupling on the two-vibron dynamics in an -helix protein is studied within a modified Davydov mode…
