Fig. 5.

Wannier diagram of graphene–hBN moiré at 1.5 K. Top—Landau fan of longitudinal resistivity at $D=0$, for the same Hall bar as in Fig. 4B. Bottom–Hofstadter energy spectrum features observed in the Landau fan measurement. Gaps in the fractal Hofstadter energy spectrum emanating from charge neutrality ($s=0$, $t=\pm 2,6,10,14,...$) and from the graphene–hBN superlattice miniband edge ($s=-4$, $t=\pm 2,6,10$) are indicated by gray lines. At magnetic fields where these gaps intersect ($\varphi /{\varphi }_0=1/m$ for $m=5,6,7,8,9$) are local minima in ${\rho }_{\mathit{xx}}$, marked by red lines (clearest at higher $n/n_s$). Indications of broken-symmetry states with $(s,t)=(-2,-8)$ and $(-2,-10)$ are marked by blue lines.
