Webb4 mars 2024 · It will always be a real function, yes. If the impulse response is a sine or a cosine function you may represent it as a complex exponential function just for simplifying subsequent calculations. At the very end of the calculations you have to get back to the real function. Example: cos(t - 2) = Re(exp(i*(t - 2))) where i = sqrt(-1) WebbThe popular model of composite fermions, proposed in order to rationalize FQHE, were insufficient in view of recent experimental observations in graphene monolayer and bilayer, in higher Landau levels in GaAs and in so-called enigmatic FQHE states in the lowest Landau level of GaAs.
