The Vacuum's Photon Collision Moved Toward a Tabletop Test
Standing-wave laser interferometers could probe quantum-electrodynamic photon scattering without an external magnetic field.
Summary
Standing-wave laser interferometers could probe quantum-electrodynamic photon scattering without an external magnetic field.
The proposal uses conventional laser sources inside standing-wave interferometers to look for photon-photon interactions in the matter vacuum. Sensitivity improves nonlinearly with circulating cavity power, which the authors argue brings the quantum-electrodynamic signal within reach of laboratory-scale experiments. They also outline adaptations for fields beyond the Standard Model. This is a theoretical experimental design, not a reported detection of vacuum nonlinearity or new particles.
