Quantum dots based on parabolic quantum wells: importance of electronic correlations
T. Ihn, C. Ellenberger, C. Yannouleas +4
We present measurements and theoretical interpretation of the magnetic field dependent excitation spectra of a two-electron quantum dot. The quantum dot is based on an AlGa$_{1…
Bosonic molecules in rotating traps
Igor Romanovsky, Constantine Yannouleas, Leslie O. Baksmaty +1
We present a variational many-body wave function for repelling bosons in rotating traps, focusing on rotational frequencies that do not lead to restriction to the lowest Landau lev…
Electron and boson clusters in confined geometries: symmetry breaking in quantum dots and harmonic traps
Constantine Yannouleas, Uzi Landman
We discuss the formation of crystalline electron clusters in semiconductor quantum dots and of crystalline patterns of neutral bosons in harmonic traps. In a first example, we use…
Symmetry breaking and Wigner molecules in few-electron quantum dots
Constantine Yannouleas, Uzi Landman
We discuss symmetry breaking in two-dimensional quantum dots resulting from strong interelectron repulsion relative to the zero-point kinetic energy associated with the confining p…
From a few to many electrons in quantum dots under strong magnetic fields: Properties of rotating electron molecules with multiple rings
Yuesong Li, Constantine Yannouleas, Uzi Landman
Using the method of breaking of circular symmetry and of subsequent symmetry restoration via projection techiques, we present calculations for the ground-state energies and excitat…
