Structure and conductance histogram of atomic-sized Au contacts
M. Dreher, F. Pauly, J. Heurich +3
Many experiments have shown that the conductance histograms of metallic atomic-sized contacts exhibit a peak structure, which is characteristic of the corresponding material. The o…
Persistent Spin Currents in Helimagnets
Jan Heurich, Jürgen König, A. H. MacDonald
We demonstrate that weak external magnetic fields generate dissipationless spin currents in the ground state of systems with spiral magnetic order. Our conclusions are based on phe…
Conductance of a hydrogen molecule
J. Heurich, F. Pauly, J. C. Cuevas +2
Recently Smit et al. [Nature 419, 906 (2002)] have reported that a single hydrogen molecule can form a bridge between Pt electrodes, which has a conductance close to one quantum un…
Electrical transport through single-molecule junctions: from molecular orbitals to conduction channels
J. Heurich, J. C. Cuevas, W. Wenzel +1
We present an atomistic theory of electronic transport through single organic molecules that reproduces the important features of the current-voltage characteristics observed in re…
Subharmonic Shapiro steps and assisted tunneling in superconducting point contacts
J. C. Cuevas, J. Heurich, A. Martin-Rodero +2
We analyze the current in a superconducting point contact of arbitrary transmission in the presence of a microwave radiation. The interplay between the ac Josephson current and the…
Instabilities and self-socillations in atomic four-wave mixing
J. Heurich, H. Pu, M. G. Moore +1
The development of integrated, waveguide-based atom optical devices requires a thorough understanding of nonlinear matter-wave mixing processes in confined geometries. This paper a…
