Sagnac effect in relativistic and nonrelativistic physics

  title={Sagnac effect in relativistic and nonrelativistic physics},
  author={Jeeva Anandan},
A simple special-relativistic derivation of the Sagnac effect, which reconciles the earlier general-relativistic and nonrelativistic derivations, is given. A distinction is made between the ''classical Sagnac effect'' and the ''quantum Sagnac effect.'' A new group-theoretic derivation of these effects is also given. It is pointed out that there must exist a phase shift due to the Thomas precession in the interference of particles with intrinsic spin. The group-theoretic treatment also… CONTINUE READING
