Gravitational waves in f (R, T)-rainbow gravity: even modes and the Huygens principle

O Aydogdu, M Salti - Physica Scripta, 2022 - iopscience.iop.org
In the context of f (R, T)-gravity, propagation of gravitational waves (GWs) for even (or polar)
modes is explored by using the Regge-Wheeler gauge in the conformally flat Friedman …

Creation of fermions in a two-dimensional de Sitter space via a quantum gravity approach
