摘要：
We study the departures from classical synchrotron radiation due to the noncommutativity of the coordinates. We find that these departures are significant but do not give tight bounds on the magnitude of the noncommutative parameter. On the other hand, these results could be used in future investigations in this direction. We also find an acausal behavior for the electromagnetic field due to the presence in the theory of two different speeds of light. This effect naturally arises even if only theta(12) is different from zero.
