Beyond general relativity: gravitational waves in non-minimally coupled theories
Stephon Alexander, Tatsuya Daniel, Tucker Manton
Non-minimal couplings between matter and curvature tensors arise in many different contexts. Such couplings modify solutions of general relativity (GR) and therefore can be probed…
Gravitational Waves in Chern-Simons-Gauss-Bonnet Gravity
Tatsuya Daniel, Leah Jenks, Stephon Alexander
It is known that the four-dimensional effective field theory arising from heterotic string theory is general relativity with both a Chern-Simons and Gauss-Bonnet term. We study the…
An SZ-Like Effect on Cosmological Gravitational Wave Backgrounds
Tatsuya Daniel, Marcell Howard, Morgane König
Cosmological gravitational wave backgrounds (CGWBs) are the conglomeration of unresolved gravitational wave signals from early Universe sources, which make them a promising tool fo…
An Exact Fermionic Chern-Simons-Kodama State in Quantum Gravity
Stephon Alexander, Tatsuya Daniel, Marcell Howard +1
The Chern-Simons-Kodama (CSK) state is an exact, non-perturbative wave function in the Ashtekar formulation of classical General Relativity. In this work, we find a generalized fer…
