Topology-induced many body effects in hydrogenated Pt nanocontacts
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...

| 520 | 3 | |a 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. |l eng | |
