Oscillating Resonances: Imprints of ultralight dark matter at colliders
Martin Bauer, Sreemanti Chakraborti
In models where ultralight fields constitute dark matter, the misalignment mechanism leads to coherent, low-amplitude oscillations in fundamental constants. This effect arises from…

On the Validity of Bounds on Light Axions for GeV
Martin Bauer, Sreemanti Chakraborti
Light bosonic dark matter fields that can be treated like a classical wave have non-linear field values close to massive bodies. Here we make the important observation that the qua…

Axion Bounds from Quantum Technology
Martin Bauer, Sreemanti Chakraborti, Guillaume Rostagni
A consistent treatment of the quantum field theory of an axion-like particle (ALP) interacting with Standard Model fields requires to account for renormalisation group running and…
