On the APM power spectrum and the CMB anisotropy: Evidence for a phase transition during inflation?

Abstract:

Adams et al. (1997b) have noted that according to our current understanding of the unification of fundamental interactions, there should have been phase transitions associated with spontaneous symmetry breaking {\em during} the inflationary era. This may have resulted in the breaking of scale-invariance of the primordial density perturbation for brief periods. A possible such feature was identified in the power spectrum of galaxy clustering in the APM survey at the scale $k \sim 0.1 h$ Mpc^{-...
