Structure and stability of superfluid (formula presented) systems with cylindrical symmetry
The structure and stability of superfluid (formula presented) systems with cylindrical symmetry are studied. Ground-state energies and density profiles are computed by using density-functional approaches. A model to understand the energetics of cylindrical systems is developed by following the main...
