Pure connection gravity at one loop: Instanton background
Kai Groh, Kirill Krasnov, Christian F. Steinwachs
In the "pure connection" formulation General Relativity becomes a particular diffeomorphism invariant SL(2) gauge theory. Using this formalism, we compute the divergent contributio…
Duality and Couplings of 3-Form-Multiplets in N=1 Supersymmetry
Kai Groh, Jan Louis, Jason Sommerfeld
In this paper we study 3-form gauge fields in four-dimensional N=1 supersymmetric theories. We give the sigma model action together with its Poincare dual action for massless and m…
Off-diagonal heat-kernel expansion and its application to fields with differential constraints
Kai Groh, Frank Saueressig, Omar Zanusso
The off-diagonal heat-kernel expansion of a Laplace operator including a general gauge-connection is computed on a compact manifold without boundary up to third order in the curvat…
Higher Derivative Gravity from the Universal Renormalization Group Machine
F. Saueressig, K. Groh, S. Rechenberger +1
We study the renormalization group flow of higher derivative gravity, utilizing the functional renormalization group equation for the average action. Employing a recently proposed…
The Universal RG Machine
Dario Benedetti, Kai Groh, Pedro F. Machado +1
Functional Renormalization Group Equations constitute a powerful tool to encode the perturbative and non-perturbative properties of a physical system. We present an algorithm to sy…
Ghost wave-function renormalization in Asymptotically Safe Quantum Gravity
Kai Groh, Frank Saueressig
Motivated by Weinberg's asymptotic safety scenario, we investigate the gravitational renormalization group flow in the Einstein-Hilbert truncation supplemented by the wave-function…
