Download or read book Spin In Gravity Is It Possible To Give An Experimental Basis To Torsion written by Venzo De Sabbata and published by World Scientific. This book was released on 1998-07-08 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of spin is believed to be a necessary tool if one wishes to quantize general relativity. Then the main problem is to see if the introduction of spin generalizing the general relativity from a geometric point of view, i.e. through the concept of torsion, can be experimentally verified.The reader can find in this book both theoretical and experimental arguments which show the necessity for the introduction of spin, and then of torsion, in gravity. In fact, torsion constitutes the more natural and simple way to introduce spin in general relativity. For that reason it is of fundamental importance to see if there are some experiences that indicate — if not directly, then at least indirectly — the presence of torsion. This book presents a discussion on experiments with a polarized-mass torsion pendulum, the search for galactic dark matter interacting with a spin pendulum, a description of a space-based method for determination of the gravitational constant and space-based measurements of spin in gravity, as well as a discussion on theoretical arguments, for instance the nature of torsion and nonmetricity, the viability of gravitational theories with spin-torsion and spin-spin interaction, many-dimensional gravitational theories with torsion, spinors on curved spaces, the spinors in real space-time, etc.We know that until now there has been no evidence for torsion, but this fact cannot prevent us from considering in some detail this implement of research that seems to be important from both a geometrical and a physical point of view.

Download or read book Torsion Pendulum Searches for Macroscopic Spin interactions as a Window on New Physics written by William A. Terrano and published by . This book was released on 2015 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interactions of intrinsic particle spin offer a powerful window into important aspects of new physics, such as hidden high energy symmetries and CP-violation. This dissertation describes a new spin 20-pole torsion pendulum made with alternating high and low spin-density magnets. We operated the pendulum 4.1 mm from a spin source and 2.0 mm from a mass source, reaching the thermal noise level of the torsion fiber in all of our experiments. This allowed us to probe electron spin dipole-dipole and mono-dipole interactions to greater sensitivities and over shorter distances than any previously test. We found no evidence of new interactions. Our mono-dipole experiments set new constraints for exchange boson masses of ~1- 500 [mu]eV. Our dipole-dipole experiments set new constraints for all interaction lengths, down to 10^-15 of electromagnetic strength at infinite range.

This book was released on 2007-09-04 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many new tests of gravity and, in particular, of Einstein's general relativity theory will be carried out in the near future: The Lense--Thirring effect and the equivalence principle will be tested in space; moreover, gravitational waves will be detected, and new atomic interferometers and clocks will be built for measurements in gravitational and inertial fields. New high-precision devices have made these experiments feasible. They will contribute to a better understanding of gravitational physics. Both experimental developments and the theoretical concepts are collected in this volume. Exhaustive reviews give an overall insight into the subject of experimental gravitation.

Download or read book The Search for Non Newtonian Gravity written by Ephraim Fischbach and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: A history of the attempts to test the predictions of Newtonian Gravity, describing in detail recent experimental efforts to verify both the inverse-square law and the Equivalence Principle. Interest in these questions has increased in recent years, as it has become recognised that deviations from Newtonian gravity could be a signal for a new fundamental force in nature. This is the first book devoted entirely to this subject, and will thus be useful to both graduate students and researchers interested in this field. It describes the ideas that underlie searches for such deviations, focusing on macroscopic tests. A comprehensive bibliography of some 450 entries supplements the text.

Available in PDF, EPUB and Kindle. Book excerpt: The Second Mexican Meeting on Mathematical and Experimental Physics brought together scientists from many different fields. The Meeting was divided into three Symposia: (i) Materials Science and Applied Physics, (ii) Statistical Physics and Beyond, (iii) Gravitation and Cosmology. This proceedings presents the papers of the Gravitation and Cosmology Symposium. The main goal of the Gravitation and Cosmology Symposium was to present the perspectives of scientists in the fields of cosmology and gravitation regarding their current work as well as the anticipated development of their research fields in the near future.
