Bit-number cumulants as a correlation measure of self-generated oscillations in a semiconductor model for low-temperature impurity breakdown

  • H. Naber
  • E. Schöll


A semiconductor model for self-generated, coupled oscillations in the regime of lowtemperature impurity breakdown is used to show that the bit-number cumulants of the invariant density of a dynamic system represent a measure for internal correlations between certain subsystems of this system. The bit-number cumulants appear to be an appropriate measure for linear as well as for nonlinear correlations.
