Short-Range Correlations in He-4 Liquid and Small He-4 Droplets described by the Unitary Correlation Operator Method
R. Roth, H. Feldmeier
The Unitary Correlation Operator Method (UCOM) is employed to treat short-range correlations in both, homogeneous liquid and small droplets of bosonic He-4 atoms. The dominating sh…

Realistic Interactions and Configuration Mixing in Fermionic Molecular Dynamics
T. Neff, H. Feldmeier, R. Roth +1
In Fermionic Molecular Dynamics the occurrence of multifragmentation depends strongly on the intrinsic structure of the many-body state. Slater determinants with narrow single-part…

Fermionic Molecular Dynamics and short range correlations
H. Feldmeier, T. Neff, R. Roth +1
Fermionic Molecular Dynamics (FMD) models a system of fermions by means of many-body states which are composed of antisymmetrized products of single-particle states. These consist…
