AbstractBased oil recently proposed U(1) x SU(2) Chern-Simons gauge field theory, an interpretation of the transport and magnetic relaxation properties of underdoped cuprates is proposed. The interplay of the doping-dependent spin gap effect and dissipation due to gauge fluctuations gives rise to a crossover from metallic to insulating behavior of conductivity its temperature decreases, ill semi;quantitative agreement with experimental data. For the same reason the magnetic relaxation rate shows a maximum nearby.
