On the vibron dressing in the one-dimensional macromolecular chains caused by the interaction with acoustic phonon modes
vibron polaron vibron–phonon interaction vibron dressing protein macromolecular chains
2012/4/20
We present a study of the physical properties of the vibrational excitation in the one-dimensional macromolecular chains, caused by the interaction with acoustical phonon modes. The influence of the t...
Explaining the observed long coherence effects by 2D photon echo experiments in photosynthetic EET : Two-Component Phonon Spectrum model
