GRM 2021 introduction

In 1918, Lense and Thirring discovered in general relativity the gravitomagnetic effect on the Moon’s orbit around Earth in the gravitational field of the rotating Sun. This Lense-Thirring frame dragging effect is important in the understanding of astrophysical phenomena. It is also important in finding the matched templates for detecting gravitational waves. Lense-Thirring precession of the orbits of LAGEOS satellites was experimentally verified. The frame-dragging on the quartz gyros on board the Gravity Probe B drag-free satellite was successfully measured. With the development of laser interferometry and atom interferometry, the precision of laser ring gyros and atom gyros improves quickly. A number of large-scale earth-based ring gyros with the aim for geophysical applications, and for measuring the Lense-Thirring effects are under development. Atom gyros and other rotation sensors are also studied by various groups.

The third international workshop on gravitomagnetism and large-scale rotation measurement (GRM) will be held in Wuhan, China, from Nov. 25th to 26th, 2021. It is organized by the Center for Gravitational Experiments, School of Physics, Huazhong University of Science and Technology. The first two GRM meetings were held in Wuhan and Rome in the years of 2018 and 2019. The meeting topics include but not limited to:

(1) Gravitomagnetism;

(2) Lense-Thirring effects in the solar system, in astrophysics and in cosmology;

(3) Large-scale laser ring gyros;

(4) Precision atom gyros and large-scale proposals;

(5) Space rotation sensors;

(6) Application to geophysics together with interferometric strain meters;

(7) Precision area metrology and geometrical stability;

(8) Other related topics
