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

Autor: Blackburn, Elizabeth, Ivashko, Oleh, Campillo, Emma, von Zimmermann, Martin, Liang, Ruixing, Bonn, Douglas A., Hardy, Walter N., Chang, Johan, Forgan, Edward M., Hayden, Stephen M.

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 informat

Removal or cancellation of noise has wide-spread applications for imaging and acoustics. In every-day-life applications, denoising may even include generative aspects, which are unfaithful to the ground truth. For scientific use, however, denoising m
