Abstract
The general relativity gyromagnetic effects of an electron close to the earth’s magnetic field, can be distinguished by thoserngenerated by the most general setting (expressing form a gravitational wave(s background)) of a test particle orbiting arnnon symmetric Kerr-Newman black hole can be analyzed at 2-5 Post-Newtonian parameterized formalisms compared (afterrnBirkoff\'s theorem of asymptotic flatness), by the suitable spectral analysis. The quantum effects can be controlled by a one-armrnMichelson interferometer, while the information about the pre-goemetry information about an ideally-emerging spacetimerncan be (at least partially) explored by interferometers. The spectral analysis reveals at the requested order the two differentrncontributions. The possible results of other theories of gravitations, which include Einsteinian gravity as a low-energy limit,rncan also be sampled in the spectral analysis, according to the different contributions in the detected (suitably reconstructed)rnspectrum. The lower order within the spectral analysis in the energy and in the mass/length can account for other phenomena.rnBoth single interferometers and coupled interferometers can be considered. The developments of technical improvements ofrninterferometers, as well as the appropriate application of computer-based techniques for the electrically-converted signal will bernanalyzed. This spectral analysis allows to discern from modified theories of gravity, also within the most general reformulation,rndue to a different order (2-3) in the spectral analysis.
