DOI: 10.1007/jhep08(2017)004
Abstract: A bstractBuilding on recent advances in the understanding of gauge-Yukawa theories we explore possibilities to UV-complete the Standard Model in an asymptotically safe manner. Minimal extensions are based on a large flavor sector of additional… read more here.

DOI: 10.1103/physrevd.103.026006
Abstract: We explore the phenomenology of scalar fields coupled to asymptotically safe quantum gravity, in light of their potential significance for dark matter, for the inflaton as well as dynamical dark energy, and in the Higgs… read more here.

DOI: 10.1103/physrevd.97.085008
Abstract: We study interacting fixed points and phase diagrams of simple and semi-simple quantum field theories in four dimensions involving non-abelian gauge fields, fermions and scalars in the Veneziano limit. Particular emphasis is put on new… read more here.

DOI: 10.1103/physrevd.98.043505
Abstract: We consider an inflationary model motivated by quantum effects of gravitational and matter fields near the Planck scale. Our Lagrangian is a resummed version of the effective Lagrangian recently obtained by Demmel, Saueressig, and Zanusso… read more here.

DOI: 10.1103/physrevlett.122.211601
Abstract: All known examples of four-dimensional quantum field theories with asymptotic freedom or asymptotic safety at weak coupling involve non-Abelian gauge interactions. We demonstrate that this is not a coincidence: No weakly coupled fixed points, ultraviolet… read more here.

DOI: 10.1103/physrevlett.123.101301
Abstract: A key incentive of quantum gravity is the removal of spacetime singularities plaguing the classical theory. We compute the nonperturbative momentum dependence of a specific structure function within the gravitational asymptotic safety program which encodes… read more here.
