Scale-invariant inflation
Massimiliano Rinaldi, Chiara Cecchini, Anish Ghoshal +1
We examine a scalar-tensor model of gravity that is globally scale-invariant. When adapted to a spatially flat Robertson-Walker metric, the equations of motion describe a dynamical…

Inflationary helical magnetic fields with a sawtooth coupling
Chiara Cecchini, Massimiliano Rinaldi
We study the generation of helical magnetic fields during inflation by considering a model which does not suffer from strong coupling or large back-reaction. Electromagnetic confor…
