Abstract

We systematically calculate localization length and conductance fluctuations in quantum wires with spin-orbit interaction to demonstrate that the effective symmetry of the system is determined by the relative magnitude between the spin-relaxation length and the localization length. When the localization length is much smaller than the spin-relaxation length, the localization length is close to the value of wires without spin-orbit interaction. When the localization length exceeds the spin-relaxation length, the localization length is enhanced and approaches that of wires with strong spin-orbit interaction. The same symmetry crossover occurs in conductance fluctuations.
