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…

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…
