摘要：

Landauer's residual resistivity dipole is studied in a system with multiple coherent scatterings. The particle density distribution within a mesoscopic conductor under nonequilibrium conditions is calculated and shown to have fluctuations with both short- and long-range correlations. In a charged system, these fluctuations significantly modify the internal electrical field and may be probed using nuclear quadrupole resonance.
