Abstract
The bulk conductivity of a two-dimensional system is studied assuming that quantum interference effects break time-reversal symmetry in the presence of strong spin-orbit interaction and strong lattice potential. The study is carried out by direct diagonalization in order to explore the nonlinear-response regime. The system displays a quantized conductivity that depends on the intensity of the electric field and under specific conditions the conductivity limit at zero electric field shows a nonvanishing value.
