摘要: We begin with an overview of the experimental results for temperature and doping dependences optical-conductivity spectral weight in cuprate superconductors across whole phase diagram. Then we discuss recent attempts to explain observed behavior using reduced full models unconventional dx2−y2 charge-density waves.
