Cohesion, Conductance, and Charging Effects in a Metallic Nanocontact
C. A. Stafford, F. Kassubek, J. Bürki +2
The conducting and thermodynamic properties of ballistic metallic nanocontacts with smooth shapes are investigated. All properties are related to the electronic scattering matrix,…
The electrostatic potential profile along a biased molecular wire: A model quantum mechanical calculation
Stéphane Pleutin, Hermann Grabert, Gert-Ludwig Ingold +1
We study the electrostatic potential of a molecular wire bridging two metallic electrodes in the limit of weak contacts. With the use of a tight-binding model including a fully thr…
On the electrostatic potential profile in biased molecular wires
Abraham Nitzan, Michael Galperin, Gert-Ludwig Ingold +1
The potential profile across a biased molecular junction is calculated within the framework of a simple Thomas-Fermi type screening model. In particular, the relationship between t…
Cohesion and Stability of Metal Nanowires: A Quantum Chaos Approach
C. A. Stafford, F. Kassubek, H. Grabert
A remarkably quantitative understanding of the electrical and mechanical properties of metal wires with a thickness on the scale of a nanometer has been obtained within the free-el…
Exact c-number Representation of Non-Markovian Quantum Dissipation
J. Stockburger, H. Grabert
The reduced dynamics of a quantum system interacting with a linear heat bath finds an exact representation in terms of a stochastic Schr{ö}dinger equation. All memory effects of th…
Identification of Coulomb blockade and macroscopic quantum tunneling by noise
Hermann Grabert, Gert-Ludwig Ingold
The effects of Macroscopic Quantum Tunneling (MQT) and Coulomb Blockade (CB) in Josephson junctions are of considerable significance both for the manifestations of quantum mechanic…
