Effects of scarring on quantum chaos in disordered quantum wells

J. Keski-Rahkonen, P. J. J. Luukko, S. Åberg +1

The suppression of chaos in quantum reality is evident in quantum scars, i.e., in enhanced probability densities along classical periodic orbits, providing opportunities in control…

-decay calculations of heavy nuclei using an effective Skyrme interaction

D. E. Ward, B. G. Carlsson, S. Åberg

Background: For nuclei heavier than Pb decay is a dominating decay mode, and in the search of new superheavy elements one often observes chains of decays. Purpose:…

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…

Superscars in billiards -- A model for doorway states in quantum spectra

S. Åberg, T. Guhr, M. Miski-Oglu +1

In a unifying way, the doorway mechanism explains spectral properties in a rich variety of open mesoscopic quantum systems, ranging from atoms to nuclei. A distinct state and a bac…

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…

Mesoscopic Fluctuations of the Pairing Gap

S. Åberg, H. Olofsson, P. Leboeuf

A description of mesoscopic fluctuations of the pairing gap in finite-sized quantum systems based on periodic orbit theory is presented. The size of the fluctuations are found to d…
