Mode truncations and scattering in strong fields
MetadataShow full item record
Truncating quantum field theories to a dominant mode offers a nonperturbative approach to their solution. We consider here the interaction of charged scalar matter with a single mode of the electromagnetic field. The implied breaking of explicit Lorentz invariance prompts us to compare instant-form quantization and front form, with the latter yielding significant simplifications when light-front zero modes are included. Using these field theory results we reassess the validity of existing first-quantized approaches to depletion effects in strong laser fields, and propose an alternative interpretation based on the dressing approach to QED and its infrared structure.
