Abstract:
It is shown that recent experimental data on transport through Pt nanocontacts in the presence of hydrogen admit an explanation in terms of topological and electronic correlation grounds. A model Hamiltonian, which incorporates two orbitals on Pt atoms, a single orbital on hydrogens, and the on-site Coulomb repulsion on the H atoms, is solved exactly, and connected to Pt leads described by a Bethe lattice. When two weakly coupled H atoms are placed between the Pt electrodes transversally to the transport direction (as recently suggested) many body effects related to the symmetry of the Pt-H couplings, stabilize the conductance around one quantum with a single channel contributing to the current, in agreement with the experiments. © 2005 The American Physical Society.
