Signatures of High-Frequency Gravitational Waves in Electromagnetic Cavities
Sebastian Schenk, Kristof Schmieden, Pedro Schwaller
Similar to axions, gravitational waves (GW) can induce oscillating electromagnetic fields inside electromagnetic cavities. We explore their experimental sensitivity to monochromati…

Exploring Nonperturbative Behaviour of Moments and Cumulants in Quantum Theories
Sebastian Schenk
The dynamics of quantum fields become nonperturbative when their interactions are probed by a large number of particles. To explore this regime we study correlation functions which…

A Coordinate-Independent Formalism for Detecting High-Frequency Gravitational Waves
Wolfram Ratzinger, Sebastian Schenk, Pedro Schwaller
In an external electric or magnetic field, a gravitational wave (GW) may be converted into electromagnetic radiation. We present a coordinate-invariant framework to describe the GW…
