Spin-spin interactions in solids from mixed all-electron and pseudopotential calculations a path to screening materials for spin qubits

Krishnendu Ghosh, He Ma, Mykyta Onizhuk +2

Understanding the quantum dynamics of spin defects and their coherence properties requires accurate modeling of spin-spin interaction in solids and molecules, for example by using…
