Vacuum Amplification of Chiral Gravitational Waves and the Stochastic Gravitational Wave Background
Stephon Alexander, Heliudson Bernardo, Yiya Selina Li +1
We investigate cosmological vacuum amplification of gravitational waves in dynamical Chern-Simons gravity. We develop a comprehensive framework to compute graviton production induc…
A Dark Matter Fermionic Quantum Fluid from Standard Model Dynamics
Stephon Alexander, Heliudson Bernardo, Humberto Gilmer
We present a model of dark matter as a superconducting fluid of Cooper pairs of right handed neutrinos or of vector-like quarks. The superconducting dark matter is induced by attra…
The Non-triviality of Dynamical Chern-Simons Gravity and the Standard Model
Stephon Alexander, Heliudson Bernardo, Cyril Creque-Sarbinowski
Given the growing interest in gravitational-wave and cosmological parity-violating effects in dynamical Chern-Simons (dCS) gravity, it is crucial to investigate whether the scalar-…
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…
