Evaluation of enhanced frame-dragging in the vicinity of a rotating niobium superconductor, liquid helium and a helium superfluid

Abstract

Tajmar and de Matos predicted that rotating superconductors or superfluids might produce large non-classical frame-dragging fields in order to explain a reported Cooper-pair mass anomaly in niobium. Also anomalous gyroscope signals close to the measurement resolution in the proximity of rotating superconductors or liquid helium were reported while trying to investigate this theoretical concept. Based on lessons from various setups, we succeeded in building an experimental facility that allowed us to rotate a niobium superconductor, liquid helium, superfluid helium and low temperature matter with high accelerations at high speed exceeding all previous efforts. A military-grade SRS-1000 gyroscope at close proximity in different locations was used to measure any anomalous frame-dragging-like fields. No such anomalies were found within three times the noise level of our setup (±5 × 10 −8 rad/s). Measurements with an electric motor at speeds up to 5000 RPM enabled us to set low boundaries for any coupling or frame-dragging-like effect outside of a rotating niobium superconductor or liquid helium to 4 × 10 −11 and for superfluids to 3 × 10 −10. Due to the high speeds used, these results are up to two orders of magnitude below any previous result.

Gravitational-Magnetic-Electric Interaction in Controlling Relative Permittivity and Permeability

“…Therefore, a large gravitational effect may be produced in these experiments. [2,3,6,13] We noticed that, in 5 experiments [15][16][17][18][19] the null result was reported. But, the conditions, such as the value of the electric/magnetic field, in these experiments are different.…”

“…[2][3][4][5] may be the supporters of our work and in Refs. [15][16][17][18][19] the magnetic field is omitted. So, it is too arbitrary to claim that the gravitational effect of the electric/magnetic field has been unproven from these experiments [15][16][17][18][19].…”

“…Therefore, the effect is disputed experimentally and theoretically. [14][15][16][17][18][19] Here, we present that, the gravitational effect of superconductor [2][3][4][5] could be understood and explained with the equations for the gravitational-electric-magnetic interaction. [21] Further, we theoretically demonstrate that a very large effect that the gravitational acceleration of the Earth varied by the controlling permittivity and permeability could be arrived at.…”

“…The gravitational effect of superconductor was reported [2][3][4][5][6][7][8] while it was disputed experimentally and theoretically. [14][15][16][17][18][19][20] Now, there has not been an accepted theoretical explanation for it. But, from our work, if Eq.…”

Design and First Measurements of a Superconducting Gravity-Impulse-Generator

“…One of us (MT) previously published 16,17 some anomalous signals recorded by accelerometers and laser gyroscopes close to mechanically rotating superconductors or matter at liquid helium temperatures. It was speculated that the acceleration of Cooper-pairs may produce a gravity-like field that was picked up by the sensors.…”
