Tajmar's Gravitomagntic Effect

Here I propose an idea to explain Tajmar's measurements.
Each electron-hole pair couples very weakly to the gravity field frame attached to the Earth. Since the Earth is rotating it produces a local rotation, this rotation produces a parity violation between the North Hemisphere and the South Hemisphere. The groups that have measured this effect are one in Austria and the other in Australia. The measured asymmetry confirms this parity breakdown.
Now, how can a small gravitomagnetic effect be observed?
There is at least a factor of at most 10²³ to help in the observation, the amount of elementary particles in any macroscopic piece of matter. All that is needed is a coherent response. That is, all the elementary particles have to act like a single macroscopic object. That is what superconductivity could do in these observations.
Coherent matter may be behind amplifying this small gravitomagnetic effect to big measurable parity breaking effects.
