Kerr-Schild metrics in teleparallel gravity
Markus B. Fröb
We show that the Kerr-Schild ansatz can be extended from the metric to the tetrad, and then to teleparallel gravity where curvature vanishes but torsion does not. We derive the equ…

One-loop quantum gravitational backreaction on the local Hubble rate
Markus B. Fröb
We determine corrections to the Hubble rate due to graviton loops in a cosmological background spacetime of constant deceleration parameter. The corrections are gauge-invariant, ba…
