Electron state tomography from quasiparticle interference maps
A. Razanajatovo, J. Cayssol, C. Dutreix
Characterizing electronic band structures requires precise knowledge of wave functions and their quantum geometry. Here, we introduce a tomography method to reconstruct the density…

Experimental evidence of the topological obstruction in twisted bilayer graphene
F. Mesple, P. Mallet, G. Trambly de Laissardière +4
The rich physics of magic angle twisted bilayer graphene (TBG) results from the Coulomb interactions of electrons in flat bands of non-trivial topology. While the bands' dispersion…
