De Sitter Breaking in Field Theory
R. P. Woodard
I argue against the widespread notion that manifest de Sitter invariance on the full de Sitter manifold is either useful or even attainable in gauge theories. Green's functions and…
Quantum Effects during Inflation
R. P. Woodard
The expansion of spacetime alters the energy-time uncertainty principle, allowing virtual particles to persist longer than in flat space. For a given expansion the effect is larges…
Fermion Self-Energy during Inflation
R. P. Woodard
I report on work done with Tomislav Prokopec (Heidelberg, CERN). We computed the one loop self-energy of a massless fermion during inflation. When the fermion is free it experience…
Effective Field Equations of the Quantum Gravitational Back-Reaction on Inflation
R. P. Woodard
Quantum gravitational back-reaction offers the potential of simultaneously resolving the problem of the cosmological constant and providing a natural model of inflation in which sc…
Particles As Bound States In Their Own Potentials
R. P. Woodard
I consider the problem of computing the mass of a charged, gravitating particle in quantum field theory. It is shown how solving for the first quantized propagator of a particle in…
