Resonant optical cooling of nuclear spins in case of strong Knight field of photoexcited electrons

Kirill Kavokin

Strong Knight field from photoexcited electrons lets resonant nuclear cooling produce an Overhauser field that reshapes the Hanle curve of carrier spin polarization.

Claims

C1strongest claim

in the case of strong Knight field of charge carriers, exceeding local fields of the dipole-dipole interaction of nuclear spins, the Overhauser field arising as a result of resonant cooling can considerably modify the overall shape of magnetic-field dependences of charge carrier spin polarization, experimentally observed as the Hanle effect

C2weakest assumption

The Knight field of charge carriers exceeds local fields of the dipole-dipole interaction of nuclear spins, allowing resonant cooling to produce a dominant Overhauser field

C3one line summary

Resonant nuclear spin cooling under strong Knight field produces an Overhauser field that modifies the Hanle effect shape.
