Nonlinear breatherlike localized modes in C 60 nanocrystals

Savin, Alexander; Kivshar, Yuri


We study the dynamics of nanoclusters composed of C 60 fullerene molecules. We reveal that such composite nanostructures can support long-lived strongly localized nonlinear modes, which resemble discrete breathers in simple nonlinear lattices. In these localized modes, the vibrational energy density is localized predominantly at one of the C 60 molecules, and it decays rapidly away from the mode. Our numerical simulations demonstrate that, at room temperatures, the lifetime of such nonlinear...[Show more]
