Abstract
Recent experiments have addressed the nature of the charge order seen in underdoped cuprates. Here I show that x-ray absorption and linear dichroism are excellent probes of such order. Ab initio calculations reveal that a -wave charge density wave order involving the oxygen ions is a much better description of the data than alternate models.
