Gravitational Waves from Confinement in Yang-Mills Theory
Stephan Huber, Rory Phipps, Manuel Reichert
We provide a detailed analysis of the gravitational wave spectrum of pure Yang-Mills theory. The confinement phase transition is described with an effective Polyakov loop m…
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…
Cosmology from asymptotically safe Proca theories
Carlos Pastor-Marcos, Lavinia Heisenberg, Ãlvaro Pastor-Gutiérrez +2
Effective field theories for cosmology offer a powerful framework to investigate the dynamics of space--time and address longstanding open puzzles. In this work, we initiate a prog…
Towards Two-to-Two Scattering of Scalars in Asymptotically Safe Quantum Gravity
Angelo P. Chiesa, Jan M. Pawlowski, Manuel Reichert
We compute the graviton-mediated two-to-two scattering amplitude and cross section for scalar particles in asymptotically safe quantum gravity. Specifically, we compute the full mo…
Yukawa interactions in Quantum Gravity
Gustavo P. de Brito, Manuel Reichert, Marc Schiffer
We present the first complete next-to-leading-order analysis of a Yukawa system within the framework of asymptotically safe quantum gravity. Our results are obtained through a syst…
Self-consistent graviton spectral function in Lorentzian quantum gravity
Jan M. Pawlowski, Manuel Reichert, Jonas Wessely
We present the first fully self-consistent computation of the graviton spectral function in quantum gravity, using the spectral renormalisation group for gravity put forward in arX…
