Scaling solutions for gauge invariant flow equations in dilaton quantum gravity
Yadikaer Maitiniyazi, Christof Wetterich, Masatoshi Yamada
We discuss the ultraviolet fixed point of asymptotically safe dilaton quantum gravity. It differs from the Reuter fixed point by the dependence of the Planck mass on a scalar field…
Emergence of dynamical tensor fields in composite models of gravity
Yadikaer Maitiniyazi, Masatoshi Yamada
We investigate composite models of gravity and explore how dynamical tensor fields can emerge within the functional renormalization group framework. We consider two prototype model…
Essential Renormalization Group Equation for Gravity coupled to a Scalar field
Nobuyoshi Ohta, Masatoshi Yamada
We study the essential renormalization group equation, in which inessential couplings are removed via field redefinitions, for Einstein gravity coupled to a massive scalar field in…
Irreversible vierbein postulate: Emergence of spacetime from quantum phase transition
Yadikaer Maitiniyazi, Shinya Matsuzaki, Kin-ya Oda +1
We formulate a model for quantum gravity based on the local Lorentz symmetry and general coordinate invariance. A key idea is the irreversible vierbein postulate that a tree-level…
Geometric realization via irrelevant deformations induced by the stress-energy tensor
Xi-Yang Ran, Feng Hao, Masatoshi Yamada
In this paper, we generalize the deformations driven by the stress-energy tensor and investigate their relation to the flow equation for the background metric at the classical…
Functional renormalization group study of a four-fermion model with violation
Linlin Huang, Mamiya Kawaguchi, Yadikaer Maitiniyazi +3
We perform a functional renormalization group analysis of a four-fermion model with and violation to explore the nonperturbative infrared dynamics of quantum chromodynamic…
