Quantum Gravitational Corrections to Electromagnetism And Backreaction
Sanjib Katuwal
This dissertation examines the impact of quantum gravity on electromagnetism and its backreaction, using perturbative general relativity as an effective field theory. Our analysis…
Perturbative Quantum Gravity Induced Scalar Coupling to Electromagnetism
S. Katuwal, R. P. Woodard
Physicists working on atom interferometers are interested in scalar couplings to electromagnetism of dimensions 5 and 6 which might be induced by quantum gravity. There is a widesp…
Reheating with Effective Potentials
S. Katuwal, S. P. Miao, R. P. Woodard
We consider reheating for a charged inflaton which is minimally coupled to electromagnetism. The evolution of such an inflaton induces a time-dependent mass for the photon. We show…
Gauge Independent Quantum Gravitational Corrections to Maxwell's Equation
S. Katuwal, R. P. Woodard
We consider quantum gravitational corrections to Maxwell's equations on flat space background. Although the vacuum polarization is highly gauge dependent, we explicitly show that t…
Inflaton Effective Potential from Photons for General
S. Katuwal, S. P. Miao, R. P. Woodard
We accurately approximate the contribution that photons make to the effective potential of a charged inflaton for inflationary geometries with an arbitrary first slow roll paramete…
