What do phase space methods tell us about disordered quantum systems?
G. -L. Ingold, A. Wobst, C. Aulbach +1
Introduction Phase space methods in quantum mechanics - The Wigner function - The Husimi function - Inverse participation ratio Anderson model in phase space - Husimi functions - I…
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…
Conductance through a One-Dimensional Correlated System: Relation to Persistent Currents and Role of the Contacts
Rafael A. Molina, Dietmar Weinmann, Rodolfo A. Jalabert +2
Based on a recent proposal [O.P. Sushkov, Phys. Rev. B 64, 155319 (2001)], we relate the quantum conductance through a sample in which electrons are strongly correlated to the pers…
Path Integrals and Their Application to Dissipative Quantum Systems
Gert-Ludwig Ingold
Introduction Path Integrals - Introduction - Propagator - Free Particle - Path Integral Representation of Quantum Mechanics - Particle on a Ring - Particle in a Box - Driven Harmon…
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…
Delocalization and Heisenberg's uncertainty relation
Gert-Ludwig Ingold, Andre Wobst, Christian Aulbach +1
In the one-dimensional Anderson model the eigenstates are localized for arbitrarily small amounts of disorder. In contrast, the Harper model with its quasiperiodic potential shows…
