Electronic and magnetic properties of small one-dimensional Wigner crystals from an ab initio approach
Daniele Lagasco, Jan Arjan Berger
The paper introduces an ab initio full‑configuration‑interaction method to compute electronic charge distributions and exchange coupling in small one‑dimensional Wigner crystals, m…

The exchange coupling of a Wigner dimer
Daniele Lagasco, Zoran Ristivojevic
We study the exchange coupling in small Wigner crystals confined to one-dimensional space. In particular we concentrate on the simplest nontrivial case of two electrons in a box po…
