INTERLAYER CHARGE DYNAMICS OF THE UNIFORM RESONATING-VALENCE-BOND STATE

The physical properties along the c axis of the uniform resonating-val ence-bond state are studied. The physical electron, i.e., the composit e particle of a spinon and a holon, hops between the layers incoherent ly. Conductivity, thermopower, thermal conductivity, and Hall constant re calculated and compared with the experiments in high-T-c cuprates. The renormalization group equation is obtained for the interlayer hop ping t(c) which is found to be marginally relevant. The effects of the spin gap are also discussed.
