Stabilization of Yang-Mills chaos in non-Abelian Born-Infeld theory

We investigate dynamics of the homogeneous time-dependent SU(2) Yang-Mills fields governed by the non-Abelian Born-Infeld Lagrangian, which arises in superstring theory as a result of summation of all orders in the string slope parameter α′. It is shown that, generically, the Born-Infeld dynamics are less chaotic than those in the ordinary Yang-Mills theory, and at a high enough field strength the Yang-Mills chaos is stabilized. More generally, a smothering effect of the string nonlocality on the behavior of classical fields is conjectured.
