Two-electron entanglement in a two-dimensional isotropic harmonic trap: Radial correlation effects in the low density limit
Przemyslaw Koscik
We study a two-dimensional system of two Coulombically interacting electrons in an external harmonic confining potential. More precisely, we present calculations for the singlet gr…
Comment on "Entanglement of two interacting bosons in a two-dimensional isotropic harmonic trap" [Phys. Lett. A 373 (2009) 3833]
Przemyslaw Koscik
The correct form of the Schmidt decomposition of the stationary wave functions for a system of two interacting particles trapped in a two-dimensional harmonic potential is given
The optimized Rayleigh-Ritz scheme for determining the quantum-mechanical spectrum
Przemyslaw Koscik, Anna Okopinska
The convergence of the Rayleigh-Ritz method with nonlinear parameters optimized through minimization of the trace of the truncated matrix is demonstrated by a comparison with analy…
Two-electron entanglement in elliptically deformed quantum dots
Przemyslaw Koscik, Anna Okopinska
Entropic entanglement measures of a two-dimensional system of two Coulombically interacting particles confined in an anisotropic harmonic potential are discussed in dependence on t…
