Title: Fractionalization and broken symmetries in the underdoped cuprates

Abstract: A number of experiments in the underdoped regime of the hole-doped cuprates have found evidence for an incommensurate bond-density wave (BDW). I'll present an analysis of the density-wave instabilities of a metal, where the electronic excitations are coupled to the fractionalized excitations of a fluctuating antiferromagnet. The resulting BDW emerging out of such a fractionalized Fermi-liquid (FL*) has wave vectors along the axial direction, with a predominantly d−wave form-factor. Various routes towards confinement transitions out of such fractionalized Fermi-liquids, leading to a BDW, will also be discussed.
