Random Walks through the Ensemble: Linking Spectral Statistics with Wavefunction Correlations in Disordered Metals
We use a random walk in the ensemble of impurity configurations to generate a Brownian motion model for energy levels in disordered conductors. Treating arc-length along the random walk as fictitous time, the resulting Langevin equation relates spectral statistics to eigenfunction correlations. Solv...
