Spectral Functions of Lorentzian Quantum Gravity
Gabriel Assant, Daniel F. Litim, Manuel Reichert
We compute spectral functions of graviton modes in Lorentzian quantum gravity, interpolating between classical general relativity and an asymptotically safe ultraviolet fixed point…

Towards theory constraints on ultralight dark matter from quantum gravity
Gabriel Assant, Astrid Eichhorn, Benjamin Knorr
Ultralight scalar dark matter may couple to the Standard Model through dimension-five operators that contain the field-strength tensors of the gauge interactions. Recent progress i…
