Contribution

It provides new insights into the significance of correlations for predicting edge reconstruction in spin-polarized quantum dots at high magnetic fields.

Findings

Correlations significantly affect the ground state energy and chemical potential.

Correlations are crucial for estimating the transition magnetic field for edge reconstruction.

Edge reconstruction occurs at a specific transition field influenced by correlations.

Abstract

We investigate the effects of electron correlations on the ground state energy and the chemical potential of a droplet confined by a parabolic potential at high magnetic fields. We demonstrate the importance of correlations in estimating the transition field at which the first edge reconstruction of the maximum density droplet occurs in the spin polarized regime.
