A model for quantum dots is proposed, in which the motion of a few electrons in a three-dimensional harmonic oscillator potential under the influence of a homogeneous magnetic field of arbitrary direction is studied. The spectrum and the wave functions are obtained by solving the classical problem. The ground state of the Fermi-system is obtained by minimizing the total energy with regard to the confining frequencies. From this a dependence of the equilibrium shape of the quantum dot on the electron number, the magnetic field parameters and the slab thickness is found.read more

Plasmons and magnetoplasmons in semiconductor heterostructures
TL;DR: In this article, the status of the theory and experiment which can contribute to our knowledge of plasmon excitations in synthetic semiconductor heterostructures is surveyed. But, beyond the presentation of the results achieved, there is a need to examine carefully the methodologies employed to obtain such results.

Magnetic field and symmetry effects in small quantum dots
TL;DR: In this paper, a model of shell phenomena in small quantum dots with a few electrons under a perpendicular magnetic field is discussed within a simple model, and it is shown that various kinds of shell structures, which occur at specific values for the magnetic field lead to a disappearance of the orbital magnetization for particular magic numbers for noninteracting electrons.

Fluctuon effects in ferroelectric polarization switching

TL;DR: In this article, the authors show that the surface energy of a nucleus can be compensated for the depolarization field term by a redistribution of free charges, but this term alone is too large for thermal-fluctuation-aided nucleation to be possible.
