We develop a consistent analytic approach to determine the conditions under which slow-roll inflation can arise when the inflaton is the same scalar field that is responsible for the bounce in loop quantum cosmology (LQC). We find that the requiremen... Read More about Inflation in loop quantum cosmology.

We compare the predictions of the fundamentally motivated minimal coupling (^p⋅^A) and the ubiquitous dipole coupling (^x⋅^E) in the light-matter interaction. By studying the light-matter interaction for hydrogenlike atoms we find that the dipole app... Read More about P · Â vs x · Ê: Gauge invariance in quantum optics and quantum field theory.
