SUMMARY:Problems with large scale primordial magnetic fields - Ruth Durrer
  (Geneva University)

CONTACT:Camille Bonvin
DESCRIPTION:I argue that post-inflationary primordial mechanisms (e.g. cos
 mological phase transitions) cannot lead to large scale coherent magnetic 
 fields. I then show that also magnetic fields from inflation are severely 
 constrained since they initiate large fluctuations in the geometry during 
 the transition from inflation to the radiation era.
