  We investigate, in the framework of open quantum systems, the entanglement
dynamics of two circularly accelerated two-level atoms with the same
centripetal acceleration interacting with a bath of fluctuating electromagnetic
fields in the Minkowski vacuum. We assume that the two atoms rotate
synchronically with their separation perpendicular to the rotating plane, and
study the entanglement degradation, creation, revival, and enhancement by
solving the Markovian master equation. In contrast to the scalar-field case,
the entanglement dynamics is crucially dependent on the atomic polarizations in
the sense that the polarization directions may affect the entanglement decay
rate, and may determine the occurrences of entanglement creation, revival and
enhancement. Compared with the uniformly accelerated case and the thermal case,
the decay rate of entanglement for circularly accelerated atoms is larger,
while the revival and enhancement rates are smaller.
