Mean-field instability of trapped dilute boson-fermion mixtures
R. Roth, H. Feldmeier
The influence of boson-boson and boson-fermion interactions on the stability of a binary mixture of bosonic and fermionic atoms is investigated. The density profiles of the trapped…
Phase diagram of trapped degenerate Fermi gases including effective s- and p-wave interactions
R. Roth, H. Feldmeier
The influence of s- and p-wave interactions on trapped degenerate one and two-component Fermi gases is investigated. The energy functional of a multicomponent Fermi gas is derived…
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…
Stability of Trapped Ultracold Fermi Gases Using Effective s- and p-Wave Contact-Interactions
R. Roth, H. Feldmeier
The stability of trapped dilute Fermi gases against collapse towards large densities is studied. A hermitian effective contact-interaction for all partial waves is derived, which i…
Molecular Dynamics for Fermions
H. Feldmeier, J. Schnack
The time-dependent variational principle for many-body trial states is used to discuss the relation between the approaches of different molecular dynamics models to describe indist…
