In this paper, we report very detailed and fine measurement of the band structure reconstruction in the nematic phase of fully detwinned FeSe.
Han has made a very nice animated cube on the fine temperature-dependence of the disappearance of the dxz electron pocket:
Our first paper at Rice is published in PRX!
