Micro Oscillation Monitored by Entanglement    [PDF]

Werner Wong

The entanglement of two two-level atoms coupling a single-mode polarized
cavity field is studied, taken the oscillations of centers of atoms mass into
accounted, in which the system has two different initial states. The factor of
oscillation of center of mass is proposed to modify the entanglement of the two
atoms states. When the micro oscillations frequencies of the centers of mass
are very low, the factors depend on the relative oscillation displacements and
the initial phases, rather than the absolute amplitudes and reduce the
entanglement to three orders of magnitude. The fact that the entanglement
increases with the increase of the initial phases suggests that micro
oscillation can be monitored by entanglement. A possible scheme for
gravitational wave detection based on the oscillation effect is discussed.
