Photon-Photon Scattering at the High-Intensity Frontier: Paraxial Beams
Alexander Blinne, Holger Gies, Felix Karbstein +2
Our goal is to study optical signatures of quantum vacuum nonlinearities in strong macroscopic electromagnetic fields provided by high-intensity laser beams. The vacuum emission sc…
The quest for axions and other new light particles
K. Baker, G. Cantatore, S. A. Cetin +17
Standard Model extensions often predict low-mass and very weakly interacting particles, such as the axion. A number of small-scale experiments at the intensity/precision frontier a…
Laser experiments explore the hidden sector
M. Ahlers, H. Gies, J. Jaeckel +2
Recently, the laser experiments BMV and GammeV, searching for light shining through walls, have published data and calculated new limits on the allowed masses and couplings for axi…
Light from the Hidden Sector
M. Ahlers, H. Gies, J. Jaeckel +2
Optical precision experiments are a powerful tool to explore hidden sectors of a variety of standard-model extensions with potentially tiny couplings to photons. An important examp…
Accelerator Cavities as a Probe of Millicharged Particles
H. Gies, J. Jaeckel, A. Ringwald
We investigate Schwinger pair production of millicharged fermions in the strong electric field of cavities used for particle accelerators. Even without a direct detection mechanism…
Quantum effective actions from nonperturbative worldline dynamics
H. Gies, J. Sánchez--Guillén, R. A. Vázquez
We demonstrate the feasibility of a nonperturbative analysis of quantum field theory in the worldline formalism with the help of an efficient numerical algorithm. In particular, we…
