Vortices in quantum droplets: Analogies between boson and fermion systems
H. Saarikoski, S. M. Reimann, A. Harju +1
The main theme of this review is the many-body physics of vortices in quantum droplets of bosons or fermions, in the limit of small particle numbers. Systems of interest include co…
Electron correlation in metal clusters, quantum dots and quantum rings
M. Manninen, S. M. Reimann
This short review presents a few case studies of finite electron systems for which strong correlations play a dominant role. In simple metal clusters, the valence electrons determi…
Cold Fermionic Atoms in Two-Dimensional Traps -- Pairing versus Hund's Rule
M. Rontani, J. R. Armstrong, Y. Yu +2
The microscopic properties of few interacting cold fermionic atoms confined in a two-dimensional (2D) harmonic trap are studied by numerical diagonalization. For repulsive interact…
Manipulating the rotational properties of a two-component Bose gas
J. Christensson, S. Bargi, K. Karkkainen +4
A rotating, two-component Bose-Einstein condensate is shown to exhibit vortices of multiple quantization, which are possible due to the interatomic interactions between the two spe…
On the spin asymmetry of ground states in trapped two-component Fermi gases with repulsive interactions
M. Ogren, K. Karkkainen, Y. Yu +1
We examine the spin asymmetry of ground states for two-dimensional, harmonically trapped two-component gases of fermionic atoms at zero temperature with weakly repulsive short rang…
Super-shell structure in harmonically trapped fermionic gases and its semi-classical interpretation
M. Ogren, Y. Yu, S. Aberg +2
It was recently shown in self-consistent Hartree-Fock calculations that a harmonically trapped dilute gas of fermionic atoms with a repulsive two-body interaction exhibits a pronou…
