摘要：

We investigate the equilibrium and non-equilibrium electron transport in a quantum wire (QW) in the quantum Hall regime. While the equilibrium conductance of the QW is quantized reflecting the dissipation-less quantum Hall edge transport, the quantization collapses when the QW is voltage-biased with the voltages larger than the critical ones. This phenomenon is accompanied by the dynamic nuclear polarization which causes the temporal variation of the QW conductance of the order of minutes.
