Universal Charge Order in the High-Tc Superconductors

Bio

Eduardo H. da Silva Neto was born in Recife, Brazil. He obtained his B.A. in Physics and Mathematics (2008) from Amherst College, and his Ph. D. (2013) in Physics from Princeton University. Since 2013 he has been a Max-Planck-UBC postdoctoral research fellow at the Quantum Matter Institute at the University of British Columbia. His research has focused on the study of correlated electron systems, such as heavy-fermion materials and copper-oxide based superconductors, by the use of multiple spectroscopic techniques including scanning tunneling spectrocopy, resonant x-ray scattering and time-resolved angle-resolved photoemission.

Program Description

Superconductivity at temperatures much higher than what is predicted by the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity are obtained in some copper-oxide (cuprate) materials. In these cuprates, antiferromagnetism can be destabilized toward superconductivity by either hole or electron doping the material. Besides these two phases, a periodic distribution of the electronic density, or charge order (CO), has recently revived the field. In this talk I will discuss Cu L3-edge resonant X ray scattering experiments that established the universality of a CO competing with superconductivity in the holed-doped cuprates (Science 343, 393 (2014)) and the discovery of its counterpart in the electron-doped cuprates (Science 347, 282 (2015)).
