Chiral Symmetry and the Cosmological Constant
Stephon Alexander, Gabriel Herczeg, Jinglong Liu +1
In this work we provide a link between a nearly vanishing cosmological constant and chiral symmetry. This is accomplished with a modification of General Relativity coupled to a top…
Hidden-Sector Modifications to Gravitational Waves From Binary Inspirals
Stephon Alexander, Evan McDonough, Robert Sims +1
Gravitational wave astronomy has placed strong constraints on fundamental physics, and there is every expectation that future observations will continue to do so. In this work we q…
V-mode Polarization in Axion Inflation and Preheating
Stephon Alexander, Evan McDonough, Robert Sims
We study the production of primordial circular ("V-mode") polarization in axion inflation coupled to fermions and gauge fields, with special attention paid to (p)reheating. We cons…
