  We have investigated the relaxational dynamics for a protein model at various
temperatures. Theoretical analysis of this model in conjunction with numerical
simulations suggests several relaxation regimes, including a single
exponential, a power law and a logarithmic time dependence. Even though a
stretched exponential form gives a good fit to the simulation results in the
crossover regime between a single exponential and a power law decay, we have
not been able to directly deduce this form from the theoretical analysis.
