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…
Observation of Kekulé vortices induced in graphene by hydrogen adatoms
Y. Guan, C. Dutreix, H. Gonzales-Herrero +5
Fractional charges are one of the wonders of the fractional quantum Hall effect, a liquid of strongly correlated electrons in a large magnetic field. Fractional excitations are als…
Topological power pumping in quantum circuits
Jacquelin Luneau, Clément Dutreix, Quentin Ficheux +4
In this article, we develop a description of topological pumps as slow classical dynamical variables coupled by a quantum system. We discuss the cases of quantum Hall pumps, Thoule…
Wavefront dislocations reveal the topology of quasi-1D photonic insulators
C. Dutreix, M. Bellec, P. Delplace +1
Phase singularities appear ubiquitously in wavefields, regardless of the wave equation. Such topological defects can lead to wavefront dislocations, as observed in a humongous numb…
Measuring the Berry phase of graphene from wavefront dislocations in Friedel oscillations
C. Dutreix, H. González-Herrero, I. Brihuega +3
Electronic band structures dictate the mechanical, optical and electrical properties of crystalline solids. Their experimental determination is therefore of crucial importance for…
