Graviton-photon conversion on spin 0 and 1/2 particles
Finn Ravndal, Mats Sundberg
The differential cross-sections for scattering of gravitons into photons on bosons and fermions are calculated in linearized quantum gravity. They are found to be strongly peaked i…
Natural Quintessence and Large Extra Dimensions
A. Albrecht, C. P. Burgess, F. Ravndal +1
We examine the late-time (nucleosynthesis and later) cosmological implications of brane-world scenarios having large (millimeter sized) extra dimensions. In particular, recent prop…
Exponentially Large Extra Dimensions
A. Albrecht, C. P. Burgess, F. Ravndal +1
We show how the presence of a very light scalar with a cubic self-interaction in six dimensions can stabilize the extra dimensions at radii which are naturally exponentially large,…
Radiative corrections to the Casimir energy and effective field theory
Finn Ravndal, Jan B. Thomassen
We discuss radiative corrections to the Casimir effect from an effective field theory point of view. It is an improvement and more complete version of a previous discussion by Kong…
