Computer Simulation



Image_Comp_jpg

Computer simulations offer a great possibility to investigate the static and dynamic properties of polymers, glasses and proteins. The accessible length- and time-scales are ideal for a comparison with neutron scattering experiments. The atomic resolution of the simulations allows a direct comparison of the local dynamics (the incoherent scattering measures the self-motion of hydrogen atoms, the coherent scattering at high Q-values measures the local relaxation). The global chain dynamics of polymer systems can also be investigated and compared to experiments (e.g. using the neutron-spin-echo machine). Afterwards, the validity and limits of different models can be investigated using the simulations.
