Searching for the signature of a pair density wave in YBa$_2$Cu$_3$O$_{6.67}$ using high energy X-ray diffraction

Abstract

We have carried out a search for a pair density wave signature using high-energy X-ray diffraction in fields up to 16 T. We do not see evidence for a signal at the predicted wavevector. This is a report on the details of our experiment, with information on where in reciprocal space we looked.
