Fiber-Optic-Gyroscope Measurements Close to Rotating Liquid Helium
M. Tajmar, F. Plesescu
We previously reported anomalous fiber-optic gyroscope signals observed above rotating rings at temperatures close to liquid helium. Our results suggested that the liquid helium it…
Anomalous Fiber Optic Gyroscope Signals Observed above Spinning Rings at Low Temperature
M. Tajmar, F. Plesescu, B. Seifert
Precision fiber optic gyroscopes were mounted mechanically de-coupled above spinning rings inside a cryostat. Below a critical temperature (typically <30 K), the gyroscopes measure…
Search for Frame-Dragging-Like Signals Close to Spinning Superconductors
M. Tajmar, F. Plesescu, B. Seifert +2
High-resolution accelerometer and laser gyroscope measurements were performed in the vicinity of spinning rings at cryogenic temperatures. After passing a critical temperature, whi…
Measurement of Gravitomagnetic and Acceleration Fields Around Rotating Superconductors
M. Tajmar, F. Plesescu, B. Seifert +1
It is well known that a rotating superconductor produces a magnetic field proportional to its angular velocity. The authors conjectured earlier, that in addition to this so-called…
Gravitomagnetic Fields in Rotating Superconductors to Solve Tate's Cooper Pair Mass Anomaly
M. Tajmar, C. J. de Matos
Superconductors have often been used to claim gravitational anomalies in the context of breakthrough propulsion. The experiments could not be reproduced by others up to now, and th…
A Note on the Local Cosmological Constant and the Dark Energy Coincidence Problem
M. Tajmar
It has been suggested that the Dark Energy Coincidence Problem could be interpreted as a possible link between the cosmological constant and a massive graviton. We show that by usi…
Local Photon and Graviton Mass and its Consequences
M. Tajmar, C. J. de Matos
We show that non-zero masses for a spin-1 graviton (called graviphoton) leads to considerable gravitomagnetic fields around rotating mass densities, which are not observed. The sol…
Experimental Detection of the Gravitomagnetic London Moment
M. Tajmar, F. Plesescu, K. Marhold +1
It is well known that a rotating superconductor produces a magnetic field proportional to its angular velocity. The authors conjectured earlier, that in addition to this so-called…
Gravitomagnetic Fields in Rotating Superconductors due to Fractal Space-Time
C. J. de Matos, M. Tajmar
This paper has been withdrawn by the authors due to the inconsistency of the computations used for extra dimensions and the fractal dimensional approach of the paper. An updated ve…
Extended Analysis of Gravitomagnetic Fields in Rotating Superconductors and Superfluids
M. Tajmar, C. de Matos
Applying the Ginzburg-Landau theory including frame dragging effects to the case of a rotating superconductor, we were able to express the absolute value of the gravitomagnetic fie…
Weight Measurements of High-Temperature Superconductors during Phase Transition in Stationary, Non-Stationary Condition and under ELF Radiation
M. Tajmar, K. Hense, K. Marhold +1
There have been a number of claims in the literature about gravity shielding effects of superconductors and more recently on the weight reduction of superconductors passing through…
Advance of Mercury Perihelion Explained by Cogravity - Version II
Clovis Jacinto de Matos, Martin Tajmar
The theory of General Relativity explaines the advance of Mercury perihelion using space curvature and the Schwartzschild metric. We demonstrate that this phenomena can also be int…
Hypothetical Gravity Control and Implications for Spacecraft Propulsion
O. Bertolami, M. Tajmar
A scientific analysis of the conditions under which gravity could be controlled and the implications that an hypothetical manipulation of gravity would have for known schemes of sp…
Gravitomagnetic Field of a Rotating Superconductor and of a Rotating Superfluid
M. Tajmar, C. J. de Matos
The quantization of the extended canonical momentum in quantum materials including the effects of gravitational drag is applied successively to the case of a multiply connected rot…

The gravitational Poynting vector provides a mechanism for the transfer of gravitational energy to a system of falling objects. In the following we will show that the gravitational…
Induction and Amplification of Non-Newtonian Gravitational Fields
M. Tajmar, C. J. de Matos
One obtains a Maxwell-like structure of gravitation by applying the weak-field approximation to the well accepted theory of general relativity or by extending Newton's laws to time…

Coupling of Gravitation and Electromagnetism in the Weak Field Approximation
M. Tajmar, C. de Matos
Using the weak field approximation, we can express the theory of general relativity in a Maxwell-type structure comparable to electromagnetism. We find that every electromagnetic f…
