Cold Fermionic Atoms in Two-Dimensional Traps: Pairing versus Hund's Rule
(2009) In Physical Review Letters 102(6). p.1-060401- Abstract
- The microscopic properties of few interacting cold fermionic atoms confined in a two-dimensional (2D) harmonic trap are studied by numerical diagonalization. For repulsive interactions, a strong shell structure dominates, with Hund's rule acting at its extreme for the midshell configurations. In the attractive case, odd-even oscillations due to pairing occur simultaneously with deformations in the internal structure of the ground states, as seen from pair correlation functions.
