Subdiffusion in Peptides Originates from the Fractal-Like Structure of Configuration Space.
Physical Review Letters, 100(18):188103.
Molecular dynamics simulation of oligopeptide chains reveals configurational subdiffusion at equilibrium extending from 10(-12) to 10(-8) s. Trap models, involving a random walk with a distribution of waiting times, cannot account for the subdiffusion, which is found rather to arise from the fractal-like structure of the accessible configuration space.
