Quantum Hall effect in twisted bilayer graphene.
We address the quantum Hall behavior in twisted bilayer graphene transferred from the C face of SiC. The measured Hall conductivity exhibits the same plateau values as for a commensurate Bernal bilayer. This implies that the eightfold degeneracy of the zero energy mode is topologically protected despite rotational disorder as recently predicted. In addition, an anomaly appears. The densities at...

متن کاملJahn - Teller Effect in Diamond - like Carbon
The Jahn-Teller effect used semi-theoretically to analyse UV-visible spectra of the diamond like-carbon films on Si substrates. By deconvolution of UV-visible absorption spectra of the typical films, different absorption lines found. For each sample, six lines which were related to V • by Jahn-Teller effect are distinguished. Our theoretical approach based on distortion of the V • as the conseq...
متن کاملSuperlensing with twisted bilayer graphene
The charge susceptibility of twisted bilayer graphene is investigated in the Dirac cone, respectively, randomphase approximation. For small enough twist angles θ ≲ 2° , we find genuine interband plasmons, i.e., collective excitonic modes that exist in the undoped material with an almost constant energy dispersion. In this regime, the loss function can be described as a Fano resonance, and we ar...
