20. -1 is 1 μK, which is much smaller than any relevant energy scale. That is why, according to the standard model, "χ′ depends only on that happens on the scale of individual TLS's".
21. -1/2 when λ > h. This "simple geometric effect" somewhat enlarges λ and thus reduces both the elastic and the dipolar parts of U. It is not easy to evaluate the importance of the "geometric effect" with respect to that of screening by the electrodes. Whatever it may be, this does not change our conclusion that the h effects reported here come from a rduction of TLS-TLS interactions.
