Simulating Unruh Radiation in High-Intensity Laser-Electron Interactions for Near-Term Experimental Tests
The Unruh effect predicts that a uniformly accelerating observer perceives the vacuum as a thermal bath, yet direct observation remains elusive [1]. We simulate Unruh radiation in realistic high-intensity laser-electron collisions relevant to FACET-II and LUXE using fully three-dimensional Monte Carlo methods. In our model, Unruh emission is treated as scattering from a rest-frame thermal spectrum with Klein-Nishina cross sections, while nonlinear Compton radiation is computed across many harmo…
