Exact solution of the Gaunt-modified Landau-Lifshitz equation in a plane wave
Researchers derive exact solution for electron dynamics under quantum radiation reaction in a plane wave.
A new study published on arXiv analyzes electron dynamics in a plane electromagnetic wave, incorporating a quantum radiation reaction correction using a Gaunt factor.
The researchers found that in this specific geometry, the modified equation of motion retains the integrable structure of the classical problem.
An exact solution for energy evolution and four-velocity was derived, which simplifies to the classical result in the appropriate limit, offering a deterministic description of semiclassical radiation reaction.
