Slow energy relaxation of macromolecules and nanoclusters in solution.

F Piazza1, P De Los Rios, Y-H Sanejouand.   

Abstract

Many systems in the realm of nanophysics from both the living and the inorganic world display slow relaxation kinetics of energy fluctuations. In this Letter we propose a general explanation for such a phenomenon, based on the effects of interactions with the solvent. Within a simple harmonic model of the system fluctuations, we demonstrate that the inhomogeneity of coupling to the solvent of the bulk and surface atoms suffices to generate a complex spectrum of decay rates. We show for myoglobin and for a metal nanocluster that the result is a complex, nonexponential relaxation dynamics.
