Memory effect of the Kerr response to GW wave bombardment. At resonance, we have the deBroglie fundamental frequency, (i.e. compton) and after being hit with a GW, the Kerr will re-radiate with memory. Memory like in Couder.
So this memory effect combined with energy absorption and re-radiation IS QM.
Kerr ring has two frequency bands. EM band is high frequency exchange in the linear region of the singularity line, while compton – deBroglie frequency is QM.
