Query: Spin polarization through Intersystem Crossing in the silicon vacancy of
  silicon carbide   Silicon carbide (SiC)-based defects are promising for quantum communications,
quantum information processing, and for the next generation of quantum sensors,
as they feature long coherence times, frequencies near the telecom, and optical
and microwave transitions. For such applications, the efficient initialization
of the spin state is necessary. We develop a theoretical description of the
spin polarization process by using the intersystem crossing of the silicon
vacancy defect, which is enabled by a combination of optical driving,
spin-orbit coupling, and interaction with vibrational modes. By using distinct
optical drives, we analyze two spin polarization channels. Interestingly, we
find that different spin projections of the ground state manifold can be
polarized. This work helps to understand initialization and readout of the
silicon vacancy and explains some existing experiments with the silicon vacancy
center in SiC.
