Abstract
At very high radiation field intensities in vacuum, Maxwell equations need to be modified to account for the QED photon-photon interaction. We show that such modified equations support nondiffracting spatial radiation solitons that propagate for very long distances without changing their shapes. These solitons, and the underlying self-focusing and instability effects, should be observable in the near future.Keywords
