Abstract

We study the electronic structure of the ladder compounds (Formula presented) and (Formula presented) Our local-density approximation calculations for (Formula presented) give similar Cu (Formula presented) bands near the Fermi energy as reported for (Formula presented) The hopping parameters estimated by fitting these bands show a strong anisotropy between the (Formula presented) and (Formula presented) intraladder hopping and small interladder hopping. A downfolding method shows that this anisotropy arises from the ladder structure. The conductivity perpendicular to the ladders is computed assuming incoherent tunneling giving a value close to experiment.
