A Quantum Gravitational Relaxation of The Cosmological Constant
Stephon Alexander
Similar to QCD, general relativity has a sector due to large diffeomorphisms. We make explicit, for the first time, that the gravitational CP violating parameter is non-per…

Fermionic sectors for the Kodama state
Stephon Alexander, Kristin Schleich, Donald M. Witt
Diffeomorphisms not connected to the identity can act nontrivially on the quantum state space for gravity. However, in stark contrast to the case of nonabelian Yang-Mills field the…
