Charge density waves -- Shunted resistance

  1. Oct 26, 2015 #1
    In charge density wave systems in paper http://journals.aps.org/prb/abstract/10.1103/PhysRevB.37.10055
    subharmonic steps are detected in experiments from the differential resistance ##\frac{dV}{dI}##, instead of from ##I-V## characteristic. Since the charge density wave resistance is shunted by an Ohmic resistance. So in this paper authors define that when in ##\frac{dV}{dI}## curve we have jumps while in ##I-V## characteristic we will have steps. Very strange. How they really knows this?
