Comment on "Symmetry classification of bond order parameters in cuprates"

Abstract

We review the transformation of bond order waves with non-trivial form factors under time-reversal and point group symmetry. Zeyher (arXiv:1406.6846) argues that certain d-form factor states must be "flux states", but this does not apply to the form factors as defined by us (arXiv:1402.4807). The latter definitions were used in the experimental detection (arXiv:1402.5415, arXiv:1404.0362).
