Memory effects in wet granular matter — •Christoph Kohlhammer and Michael Schulz — Universität Ulm, Institut für Theoretische Physik, Albert Einstein-Allee 11, 89069 Ulm

We found that a wet granular matter model introduced on the basis of a lattice Monte-Carlo-Model shows memory effects. Those effects are typical for wet granulates as it recenly had been published in different papers dealing experimentally with this subject. The memory effects for example concern the grain density representing the opening angle of the sandpile in dependence of the degree of wetness. So we deal with a non Marcovian model behaving very senitive in the phase transition region. The memory effect allows to define a characteristic time scale.
