Strong laser fields as a probe for fundamental physics

摘要: Upcoming high-intensity laser systems will be able to probe the quantum-induced nonlinear regime of electrodynamics. So far unobserved QED phenomena such as discovery a response quantum vacuum macroscopic electromagnetic fields can become accessible. In addition, provide for flexible tool investigating fundamental physics. Primary goals consist in verifying so phenomena. Moreover, strong-field experiments search new light but weakly interacting degrees freedom and are thus complementary accelerator-driven experiments. I review recent developments this field, focusing on photon strong fields. The interaction particle-physics candidates with photons external parameterized by low-energy effective actions typically predict characteristic optical signatures. perform first estimates accessible new-physics parameter space facilities POLARIS ELI.
