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…
Signatures of Wigner Localization in Epitaxially Grown Nanowires
L. H. Kristinsdóttir, J. C. Cremon, H. A. Nilsson +5
It was predicted by Wigner in 1934 that the electron gas will undergo a transition to a crystallized state when its density is very low. Whereas significant progress has been made…
Coreless Vortices in Rotating Two-Component Quantum Droplets
H. Saarikoski, A. Harju, J. Christensson +3
The rotation of a quantum liquid induces vortices to carry angular momentum. When the system is composed of multiple components that are distinguishable from each other, vortex cor…
Universality of Many-Body States in Rotating Bose and Fermi Systems
M. Borgh, M. Koskinen, J. Christensson +2
We propose a universal transformation from a many-boson state to a corresponding many-fermion state in the lowest Landau level approximation of rotating many-body systems, inspired…
Metal clusters, quantum dots and trapped atoms -- from single-particle models to correlatio
M. Manninen, S. M. Reimann
In this review, we discuss the electronic structure of finite quantal systems on the nanoscale. After a few general remarks on the many-particle physics of the harmonic oscillator…
Mixtures of Bose gases under rotation
S. Bargi, J. Christensson, G. M. Kavoulakis +1
We examine the rotational properties of a mixture of two Bose gases. Considering the limit of weak interactions between the atoms, we investigate the behavior of the system under a…
