Can we see quantum gravity? Photons in the asymptotic-safety scenario
Babette Döbrich, Astrid Eichhorn
In the search for a quantum theory of gravity it is crucial to find experimental access to quantum gravitational effects. Since these are expected to be very small at observational…
Magnetically amplified light-shining-through-walls via virtual minicharged particles
Babette Döbrich, Holger Gies, Norman Neitz +1
We show that magnetic fields have the potential to significantly enhance a recently proposed light-shining-through-walls scenario in quantum-field theories with photons coupling to…
Magnetically amplified tunneling of the 3rd kind as a probe of minicharged particles
Babette Döbrich, Holger Gies, Norman Neitz +1
We show that magnetic fields significantly enhance a new tunneling mechanism in quantum-field theories with photons coupling to fermionic minicharged particles. We propose a dedica…
