Calculation of zero-field splitting in high-spin defects in semiconductors — •Timur Biktagirov, Wolf Gero Schmidt, and Uwe Gerstmann — Universität Paderborn, Paderborn, Germany

High-spin defects in semiconductors represent an attractive class of potential solid-state qubits [1]. One of their key spectroscopic fingerprints is the splitting of their spin sublevels in the absence of external magnetic fields. Here we discuss recent progress and open challenges in the theoretical prediction of this zero-field splitting [2, 3].
