Nuclear Reactions in Fermionic Molecular Dynamics
In the Fermionic Molecular Dynamics (FMD) approach many-body wave functions are described by Slater determinants of Gaussian wave-packets localized in phase space. The FMD wave functions can therefore describe shell model configurations and states composed of two clusters on the same footing. It is therefore natural to apply the FMD approach also to nuclear reactions. In the asymptotic region t...
متن کاملNuclear Structure Studies in Fermionic Molecular Dynamics
In the Fermionic Molecular Dynamics (FMD) approach many-body wave functions are described by Slater determinants of Gaussian wave-packets localized in phase space. The symmetries of the Hamiltonian are restored by projection on parity, angular and linear momentum. An effective interaction derived from the realistic Argonne V18 interaction by explicit introduction of short-range central and tens...
متن کاملAccelerating Fermionic Molecular Dynamics
For over fifteen years the algorithm of choice for generating lattice field theory configurations including the dynamical effect of fermions has been Hybrid Monte Carlo (HMC) [1]. Unfortunately the cost of this algorithm increases rapidly as the fermion mass m decreases; in order to keep the HMC acceptance rate Pacc constant the molecular dynamics integration step size δτ has to be reduced, and...
متن کاملFermionic Molecular Dynamics
A quantum molecular model for fermions is investigated which works with antisymmetrized many–body states composed of localized single–particle wave packets. The application to the description of atomic nuclei and collisions between them shows that the model is capable to address a rich variety of observed phenomena. Among them are shell effects, cluster structure and intrinsic deformation in gr...
