We consider the possibility of generation of the primordial magnetic field on inflation and show that the effect of the back reaction of this field can be very important. Assuming that the back rea ...

- Particle production during inflation and gravitational waves detectable by ground-based interferometers (2011, unknown): “generates only a moderate occupation number of superhorizon photons [29] and, as a consequence, is not expected to induce an important production of tensors.”
- Cosmological Magnetic Fields: Their Generation, Evolution and Observation (2013, unknown): “This problem has been noted first by Demozzi et al (2009).”
- Observable non-gaussianity from gauge field production in slow roll inflation, and a challenging connection with magnetogenesis (2012, background): “This solution has been discussed at length in [44] for all values of n, and it is unnecessary to review all their study here.”
- Adding helicity to inflationary magnetogenesis (2014, background): “Unfortunately, such choices of n are associated either to an excessive energy [9] in the electric field (n = −3) or to a strongly coupled theory [10] during inflation (n = 2).”
- Gauge fields and inflation (2012, background): “There are many works on primordial magnetic fields from inflation [55, 56, 57, 58, 59, 60, 61, 62, 63], although there exists no convincing model so far.”
- Inflationary magnetogenesis without the strong coupling problem (2013, methodology): “This is called the strong coupling problem and introduces another constraint on the coupling function, namely, f & 1 during inflation [23].”
- Cosmological magnetic fields from inflation and backreaction (2009, background): “For this case, however, the analysis is not reliable due to the strong coupling problem [6].”
