Fast energy transfer mediated by multi-quanta bound states in a nonlinear quantum lattice
Cyril Falvo, Vincent Pouthier, J. C. Eilbeck
By using a Generalized Hubbard model for bosons, the energy transfer in a nonlinear quantum lattice is studied, with special emphasis on the interplay between local and nonlocal no…
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…
Vibron-polaron critical localization in a finite size molecular nanowire
Cyril Falvo, Vincent J. C. Pouthier
The small polaron theory is applied to describe the vibron dynamics in an adsorbed nanowire with a special emphasis onto finite size effects. It is shown that the finite size of th…
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…
Theoretical Fluctuations of Conductance in Stretched Monatomic Nanowire
F. Picaud, V. Pouthier, C. Girardet +1
Recent experiments showed that the last, single channel conductance step in monatomic gold contacts exhibits significant fluctuations as a function of stretching. From simulations…
