This theoretical physics study investigates Compton scattering within the Bandos-Lechner-Sorokin-Townsend nonlinear electrodynamics framework, a theory that unifies several electromagnetic theories while preserving conformal and electromagnetic duality invariance. The researchers calculated key physical quantities including energy flux density, dispersion relations, refractive indices, wave velocities, and photon wavelength changes during Compton scattering in the presence of constant electromagnetic background fields. These calculations provide testable predictions that could experimentally validate or constrain this theoretical extension of classical electrodynamics.
Why it matters
The results offer concrete experimental predictions for testing whether electromagnetic phenomena deviate from standard Maxwell theory in extreme field conditions, which could reveal new physics beyond classical electrodynamics. Such tests are particularly relevant for understanding light propagation in strong electromagnetic environments like those near neutron stars or in high-intensity laser experiments.

Abstract: The nonlinear electrodynamics proposed by Bandos, Lechner, Sorokin and Townsend is a remarkable theory that unifies Maxwell, Bialynicki-Birula and ModMax theories, which are known theories invariant under conformal transformations and electromagnetic duality transformations. In the Bandos-Lechner-Sorokin-Townsend nonlinear electrodynamics, we calculate the energy flux density, dispersion relations, refractive indices, phase and group velocities of plane waves as well as the changes of the photon wavelength in the Compton scattering process in the presence of a constant uniform electromagnetic background. Our results are useful for testing and constraining this new theory of nonlinear electrodynamics.
