A many-particle quantum-trajectory approach for modeling electron transport and its correlations in nanoscale devices

摘要

Electron transport in mesoscopic systems is analyzed in terms of quantum (Bohm) trajectories associated to wave-function solutions of a many-particle (effective-mass) Schrodinger equation. Many-particle Bohm trajectories can be computed from single-particle Schrodinger equations. As an example, electron correlations for a triple-barrier tunneling system with electron-electron interactions are computed. Simulated noise results for interacting electrons that tunnels through triple barriers are presented. The approach opens a new path for studying electron transport and quantum noise in nanoscale systems, beyond the "Fermi liquid" paradigm.
