Charge Dynamics from Copper Oxide Materials
Shiping Feng, Zhongbing Huang
Abstract
The charge dynamics of the copper oxide materials in the underdoped and optimal doped regimes is studied within the framework of the fermion-spin theory. The conductivity spectrum shows the non-Drude behavior at low energies and unusual midinfrared peak, and the resistivity exhibits a linear behavior in the temperature, which are consistent with experiments and numerical simulations.
