For our studies, we exploit synergetic effects resulting from combined experimental and theoretical approaches. In particular, we combine nuclear magnetic resonance and molecular dynamics simulations.


Dynamic range of methods

Condensed matter with disordered structure usually shows complex dynamics on various time and length scales. Therefore, a fundamental understanding requires a characterization of structure-dynamics relations over many orders of magnitude in time and length. For this endeavor, it is necessary to combine various methods. In the Vogel group, we use both experiments and simulations.

Our methods in detail

In experimental studies, we combine, in particular, nuclear magnetic resonance and broadband dielectric spectroscopy, complemented by calorimetric measurements and neutron scattering. In computational approaches, we perform molecular dynamics simulations for all-atom and coarse-grained models. Altogether, our combined methods explore molecular dynamics from the picoseconds to the seconds regimes and on length scales from about 0.1 nanometer to 100 micrometer.

Technical developments

Development of NMR equipment

We continually develop home-built NMR equipment to open up new areas for applications. Central goals in this endeavor are the application of strong field gradients to achieve high spatial resolution or to measure slow molecular diffusion and the use of fast field cycling for broadband dynamical studies.
