Transition metal (TM) defects in silicon carbide (SiC) are a promising platform quantum technology, especially because some TM emit the telecom band. We develop theory for interaction of an active electron $D$-shell defect SiC with nuclear spin and derive effective hyperfine tensor within Kramers doublets formed by spin-orbit coupling. Based on our we discuss possibility to exchange states pote...
The spectroscopic hyperfine constants for all the alkali atoms are reported. For from lithium to cesium, only long lived atomic isotopes examined. francium, measured data nuclear ground states of available listed. All results obtained since beginning laser investigations presented, while previous works Arimondo et al. [Rev. Mod. Phys. 49, 31 (1977)] recalled. Global analyses based on scaling la...
The incommensurate spin -density –wave magnetism of Cr has attracted great interest since its discovery via neutron scattering. Although the existence of spin- density –wave has been confirmed by experiment but the calculations which have been carried out have not been able to predict the correct ground state magnetic phase for chromium yet. To predict the magnetic hyperfine field at nucleus ...
It has been proposed that valence-band holes can form robust spin qubits1–4 owing to their weaker hyperfine coupling compared with electrons5,6. However, it was demonstrated recently7–11 that the hole hyperfine interaction is not negligible, although a consistent picture of the mechanism controlling its magnitude is still lacking. Here we address this problem by measuring the hole hyperfine con...
