Podkletnov's first peer-reviewed paper on the apparent gravity-modification effect, published in 1992, attracted little notice. [3] In 1996, he submitted a longer paper, in which he claimed to have observed a larger effect (2% weight reduction as opposed to 0.3% in the 1992 paper) to the Journal of Physics D.
For example, those used in the Gravity Probe B experiment measured changes in gyroscope spin axis orientation to better than 0.5 milliarcseconds (1.4 × 10 −7 degrees) over a one-year period. [2] This is equivalent to an angular separation the width of a human hair viewed from 32 kilometers (20 miles) away.
Chin-Sen Ting is a Chinese American physicist from Taiwan and an academic.He is a distinguished professor of physics at the University of Houston. [1]Through his research, Ting has explored condensed matter theories in semiconductors, magnetism, superconductivity, and correlated electron systems, focusing on solid state systems using methods like diagrammatic many body theory and Monte Carlo ...
Eugene Podkletnov, a Russian engineer, has claimed since the early 1990s to have made such a device consisting of a spinning superconductor producing a powerful "gravitomagnetic field." In 2006, a research group funded by ESA claimed to have created a similar device that demonstrated positive results for the production of gravitomagnetism ...
A superconductor can be Type I, meaning it has a single critical field, above which all superconductivity is lost and below which the magnetic field is completely expelled from the superconductor; or Type II, meaning it has two critical fields, between which it allows partial penetration of the magnetic field through isolated points. [32]
Ceramic superconductors cannot be bolted or welded together to form superconducting junctions. Ceramic superconductors must be cast in their final shape when created. This may increase production costs. [citation needed] Ceramic superconductors can be more easily driven out of superconductivity by oscillating magnetic fields.
For crossed Andreev reflection to occur, electrons of opposite spin must exist at each normal electrode (so as to form the pair in the superconductor). If the normal material is a ferromagnet this may be guaranteed by creating opposite spin polarization via the application of a magnetic field to normal electrodes of differing coercivity.
Calculated magnetization curve for a superconducting slab, based on Bean's model. The superconducting slab is initially at H = 0. Increasing H to critical field H* causes the blue curve; dropping H back to 0 and reversing direction to increase it to -H* causes the green curve; dropping H back to 0 again and increase H to H* causes the orange curve.
