Phys. Rev. B 79, 205108 (2009) [15 pages]Correlations of the local density of states in quasi-one-dimensional wiresReceived 5 February 2009; published 11 May 2009 We report a calculation of the correlation function of the local density of states in a disordered quasi-one-dimensional wire in the unitary symmetry class at a small energy difference. Using an expression from the supersymmetric sigma model, we obtain the full dependence of the two-point correlation function on the distance between the points. In the limit of zero energy difference, our calculation reproduces the statistics of a single localized wave function. At logarithmically large distances of the order of the Mott scale, we obtain a reentrant behavior similar to that in strictly one-dimensional chains. © 2009 The American Physical Society URL:
