Crossover from weak localization to weak antilocalization in a disordered microbridge
arXiv:cond-mat/0301449 · doi:10.1103/PhysRevB.67.115313
Abstract
We calculate the weak localization correction in the double crossover to broken time-reversal and spin-rotational symmetry for a disordered microbridge or a short disordered wire using a scattering-matrix approach. Whereas the correction has universal limiting values in the three basic symmetry classes, the functional form of the magnetoconductance is affected by eventual non-homogeneities in the microbridge.
