Summary: | The frame-dragging phenomenon in gravitational fields is revisited to explore
the geometric effects induced by spacetime curvature. We quantize a massless
scalar field in the spacetime of a rotating sphere, incorporating the
frame-dragging frequency into the field modes. The excitation rate for an atom
undergoing uniform circular motion and interacting with the scalar field is
calculated. Our results reveal that the time-dependent excitation rates of
atoms following different trajectories exhibit a common envelope, from which
the frame-dragging frequency can be effectively extracted. This discovery leads
us to propose a novel detection scheme for measuring the frame-dragging
frequency caused by rotating celestial bodies, eliminating the need for
traditional starlight calibration methods. |
