Query: Bond order in two-dimensional metals with antiferromagnetic exchange
  interactions   We present an unrestricted Hartree-Fock computation of charge-ordering
instabilities of two-dimensional metals with antiferromagnetic exchange
interactions, allowing for arbitrary ordering wavevectors and internal
wavefunctions of the particle-hole pair condensate. We find that the ordering
has a dominant d symmetry of rotations about lattice points for a range of
ordering wavevectors, including those observed in recent experiments at low
temperatures on YBCO. This d symmetry implies the charge ordering is primarily
on the bonds of the Cu lattice, and we propose incommensurate bond order
parameters for the underdoped cuprates. The field theory for the onset of Neel
order in a metal has an emergent pseudospin symmetry which `rotates' d-wave
Cooper pairs to particle-hole pairs (Metlitski et al. arXiv:1005.1288): our
results show that this symmetry has consequences even when the spin
correlations are short-ranged and incommensurate.
