摘要：

Transport properties of two-dimensional charged bosons in the normal and superconducting state are derived. The Wiedemann-Franz law and the Lorentz number are obtained for the normal state. A strong suppression of the quasiparticle scattering rate and a strong enhancement of the thermal conductivity in the superconducting state are found. Temperature dependence of the in-plane thermal conductivity of YBCO crystals is explained.
