Collective Fluctuations of the Loop-Current Phase in Cuprates

ORAL

Abstract

We have calculated the collective modes of the loop-current ordered phase observed in underdoped Cuprates. Besides the modes given by the fluctuations of the Ashkin- Teller model, we find that the current fluctuations introduce a mode whose properties are similar to that of electro-magnetic vector potentials. We calculate the coupling of such a mode to the Ashkin-Teller modes and to the Fermions.
