Two-field Screening and its Cosmological Dynamics
We consider the screening of the axio-dilaton fields when both the dilaton and the axion couple to matter with Yukawa couplings. We analyze the screening of the dilaton in the vicinity of a compact object and find that this can only take place when special boundary conditions at infinity are imposed...
