Fermi molecular dynamics

Classical many body models supplemented by repulsive momentum-dependent potentials to simulate the Pauli and Heisenberg principles have been used with some success for nuclear and atomic bound state and collision problems. They are capable of describing mean ground state properties, hydrodynamics, shocks (if warranted by the physics), viscosity, correlations, clustering, and fragmentation. We have become interested in the Feldmeier Gaussian packet formulation since it is based on a variational principle using trial wave functions. We discuss some limitations of the model and discuss further directions of investigation.
