On the selective multiphoton ionization of sodium by femtosecond laser pulses: A partial-wave analysis
A. Bunjac, D. B. Popovic, N. S. Simonovic
Multiphoton ionization of sodium by femtosecond laser pulses of 800 nm wavelength in the range of laser peak intensities entering over-the-barrier ionization domain is studied. Pho…
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…
Over-the-barrier electron detachment in the hydrogen negative ion
M. Z. Milosevic, N. S. Simonovic
The electron detachment from the hydrogen negative ion in strong fields is studied using the two-electron and different single-electron models within the quasistatic approximation.…
Magnetic alteration of entanglement in two-electron quantum dots
N. S. Simonovic, R. G. Nazmitdinov
Quantum entanglement is analyzed thoroughly in the case of the ground and lowest states of two-electron axially symmetric quantum dots under a perpendicular magnetic field. The ind…
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…
