The electrical conductance of mesoscopic wires fluctuates as a function of control parameters such as the magnetic field or the applied bias voltage. We present new experimental results in the non-linear response regime at finite bias voltage. While earlier studies focused on the size of the fluctuation in the differential conductance, the present work takes a closer look at the critical field Bc (defined as the half width of the autocorrelation function) as well. The experimental findings cannot be explained by existing theoretical descriptions.
