The Cosmological Constant from a Quantum Gravitational -Vacua and the Gravitational Hall Effect
Stephon Alexander, Heliudson Bernardo, Aaron Hui
We provide a new perspective on the cosmological constant by exploring the background-independent Wheeler-DeWitt quantization of general relativity. The Chern-Simons-Kodama state o…
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…
Modified gravity approaches to the cosmological constant problem
The FADE Collaboration, Heliudson Bernardo, Benjamin Bose +5
The cosmological constant and its phenomenology remain among the greatest puzzles in theoretical physics. We review how modifications of Einstein's general relativity could allevia…
