Witryna10 lut 2024 · The impurity entropy indicates that an emergent Fibonacci anyon can be realized in the N = 2 model. We also map the case N = 2 , M = 4 to the conventional four-channel Kondo model and find the conductance at the intermediate fixed point. WitrynaSince the impurity has increased, entropy has also increased while purity has decreased. Shannon’s entropy model uses the logarithm function with base 2 (log2(P(x)) to measure the entropy because as the probability P(x) of randomly drawing a yellow ball increases, the result approaches closer to binary logarithm 1, as shown in the graph …
