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…
Effective-interaction approach to the many-boson problem
J. Christensson, C. Forssén, S. Åberg +1
We show that the convergence behavior of the many-body numerical diagonalization scheme for strongly interacting bosons in a trap can be significantly improved by the Lee-Suzuki me…
Quantum Chaos and Regularity in Ultracold Fermi Gases
M. Puig von Friesen, M. Ogren, S. Aberg
Quantum fluctuation of the energy is studied for an ultracold gas of interacting fermions trapped in a three-dimensional potential. Periodic-orbit theory is explored, and energy fl…
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…
Correlations in Nuclear Masses
H. Olofsson, S. Aberg, O. Bohigas +1
It was recently suggested that the error with respect to experimental data in nuclear mass calculations is due to the presence of chaotic motion. The theory was tested by analyzing…
