Vortices in quantum droplets: Analogies between boson and fermion systems
H. Saarikoski, S. M. Reimann, A. Harju +1
The main theme of this review is the many-body physics of vortices in quantum droplets of bosons or fermions, in the limit of small particle numbers. Systems of interest include co…
Reduced density-matrix functional theory in quantum Hall systems
E. Tölö, A. Harju
We apply reduced density-matrix functional theory to the parabolically confined quantum Hall droplet in the spin-frozen strong magnetic field regime. One-body reduced density matri…
Giant vortices in rotating electron droplets
E. Rasanen, H. Saarikoski, Y. Yu +3
We predict the formation of giant vortices in quasi-two-dimensional quantum dots at high magnetic fields, i.e., in rapidly rotating electron droplets. Our numerical results of quan…
Rectangular quantum dots in high magnetic fields
E. Räsänen, A. Harju, M. J. Puska +1
We use density-functional methods to study the effects of an external magnetic field on two-dimensional quantum dots with a rectangular hard-wall confining potential. The increasin…
Broken Symmetry in Density-Functional Theory: Analysis and Cure
A. Harju, E. Rasanen, H. Saarikoski +3
We present a detailed analysis of the broken-symmetry mean-field solutions using a four-electron rectangular quantum dot as a model system. Comparisons of the density-functional th…
Role of interactions in the far-infrared spectrum of a lateral quantum dot molecule
M. Marlo, A. Harju, R. M. Nieminen
We study the effects of electron-electron correlations and confinement potential on the far-infrared spectrum of a lateral two-electron quantum dot molecule by exact diagonalizatio…
