标题： Linear dichroism and the nature of charge order in underdoped cuprates

摘要： 最近的实验研究了欠掺杂铜氧化物中的电荷有序性质。 在这里，我展示了X射线吸收和线性二色性是研究这种有序性的优秀探针。 从头计算表明，涉及氧离子的d波电荷密度波序比其他模型更能准确描述数据。 显示英文摘要

摘要： 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 an excellent probe of such order. Ab-initio calculations reveal that a d-wave charge density wave order involving the oxygen ions is a much better description of the data than alternate models.
