Long wavelength spatial oscillations of high frequency current noise in 1D electron systems
B. Trauzettel, H. Grabert
Finite frequency current noise is studied theoretically for a 1D electron system in presence of a scatterer. In contrast to zero frequency shot noise, finite frequency noise shows…
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…
Magnetic field effects in energy relaxation mediated by Kondo impurities
G. Goeppert, Y. M. Galperin, B. L. Altshuler +1
We study the energy distribution function of quasiparticles in voltage biased mesoscopic wires in presence of magnetic impurities and applied magnetic field. The system is describe…
