    "abstract": "Fermionic Molecular Dynamics (FMD) models a system of fermions by means of\nmany-body states which are composed of antisymmetrized products of\nsingle-particle states. These consist of one or several Gaussians localized in\ncoordinate and momentum space. The parameters specifying them are the dynamical\nvariables of the model. As the repulsive core of the nucleon-nucleon\ninteraction induces short range correlations which cannot be accommodated by a\nSlater determinant, a novel approach, the unitary correlation operator method\n(UCOM), is applied. The unitary correlator moves two particles away from each\nother whenever their relative distance is within the repulsive core. The\ntime-dependent variational principle yields the equations of motion for the\nvariables. Energies of the stationary ground states are calculated and compared\nto exact many-body results for nuclei up to Ca 48. Time-dependent solutions are\nshown for collisions between nuclei.",
