Symmetry-controlled singlet-triplet transition in a double-barrier quantum ring
Heidi Potts, Josef Josefi, I-Ju Chen +6
We engineer a system of two strongly confined quantum dots to gain reproducible electrostatic control of the spin at zero magnetic field. Coupling the dots in a tight ring-shaped p…

Interplay between shell structure and trap deformation in dipolar fermi gases
J. Bengtsson, G. Eriksson, J. Josefi +2
Finite fermion systems are known to exhibit shell structure in the weakly-interacting regime, as well known from atoms, nuclei, metallic clusters or even quantum dots in two dimens…
