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…
Vortices and Edge Reconstruction in Small Quantal Systems at High Angular Momenta
M. Toreblad, Y. Yu, S. M. Reimann +2
Vortices can form when finite quantal systems are set to rotate. In the limit of small particle numbers the vortex formation in a harmonically trapped fermion system, with repulsiv…
Energy spectrum, persistent current and electron localization in quantum rings
M. Manninen, P. Koskinen, M. Koskinen +3
Energy spectra of quasi-one-dimensional quantum rings with a few electrons are studied using several different theoretical methods. Discrete Hubbard models and continuum models are…
