Shape transitions in two-body systems: two-electron quantum dots in a magnetic field
N. S. Simonovic, R. G. Nazmitdinov
We present a thorough analysis of the electron density distribution (shape) of two electrons, confined in the three-dimensional harmonic oscillator potential, as a function of the…
Entanglement as an indicator of a geometrical crossover in a two-electron quantum dot in a magnetic field
R. G. Nazmitdinov, N. S. Simonovic
We found that a downwardly concave entanglement evolution of the ground state of a two-electron axially symmetric quantum dot testifies that a shape transition from a lateral to a…
A geometrical crossover in excited states of two-electron quantum dots in a magnetic field
R. G. Nazmitdinov, N. S. Simonovic, A. R. Plastino +1
We use the entanglement measure to study the evolution of quantum correlations in two-electron axially-symmetric parabolic quantum dots under a perpendicular magnetic field. We fou…
Dynamical screening of the Coulomb interaction for two confined electrons in a magnetic field
N. S. Simonovic, R. G. Nazmitdinov
We show that a difference in time scales of vertical and lateral dynamics permits one to analyze the problem of interacting electrons confined in an axially symmetric three-dimensi…
Finite-thickness effects in ground-state transitions of two-electron quantum dots
R. G. Nazmitdinov, N. S. Simonovic
Using the exactly solvable excitation spectrum of two-electron quantum dots with parabolic potential, we show that the inclusion of the vertical extension of the quantum dot provid…
Semiclassical analysis of a two-electron quantum dot in a magnetic field: dimensional phenomena
R. G. Nazmitdinov, N. S. Simonovic, Jan M. Rost
While the dynamics for three-dimensional axially symmetric two-electron quantum dots with parabolic confinement potentials is in general non-separable we have found an exact separa…
