Query: Slow energy relaxation of macromolecules and nano-clusters in solution   Many systems in the realm of nanophysics from both the living and inorganic
world display slow relaxation kinetics of energy fluctuations. In this paper we
propose a general explanation for such 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 nano-cluster that the result is a
complex, non-exponential relaxation dynamics.
