Kerr-Schild--Kundt Metrics are Universal
arXiv:1603.06524 · doi:10.1088/1361-6382/aa60f1
Abstract
We define (non-Einsteinian) universal metrics as the metrics that solve the source-free covariant field equations of generic gravity theories. Here, extending the rather scarce family of universal metrics known in the literature, we show that the Kerr-Schild--Kundt class of metrics are universal. Besides being interesting on their own, these metrics can provide consistent backgrounds for quantum field theory at extremely high energies.
