The passage around this formula

…curvature sets. Writing the correction as a term proportional to (k/Λcurv\Lambda_{\mathrm{curv}})^2 , the fractional error in γ\gamma stays under one percent as long as the wavepacket’s momentum sits below roughly a tenth of Λcurv\Lambda_{\mathrm{curv}} ; for graphene, where Λcurv\Lambda_{\mathrm{curv}} ≈\approx 1.5×\times10^{9} inverse metres, the clean window covers momenta up to about 1.5×\times10^{8} inverse metres. Dilation is graded structured rather than exact for exactly this reason: it holds inside a window with a…
