Optical conductivity of bilayer dice lattices
P. O. Sukhachov, D. O. Oriekhov, E. V. Gorbar
We calculate optical conductivity for bilayer dice lattices in commensurate vertically aligned stackings. The interband optical conductivity reveals a rich activation behavior uniq…
Landau quantization near generalized Van Hove singularities: Magnetic breakdown and orbit networks
V. A. Zakharov, A. Mert Bozkurt, A. R. Akhmerov +1
We develop a theory of magnetic breakdown (MB) near high-order saddle points in the dispersions of two-dimensional materials, where two or more semiclassical cyclotron orbits appro…
Kondo effect in twisted bilayer graphene
A. S. Shankar, D. O. Oriekhov, Andrew K. Mitchell +1
The emergence of flat bands in twisted bilayer graphene at the magic angle can be understood in terms of a vanishing Fermi velocity of the Dirac cone. This is associated with van H…
Stackings and effective models of bilayer dice lattices
P. O. Sukhachov, D. O. Oriekhov, E. V. Gorbar
We introduce and classify nonequivalent commensurate stackings for bilayer dice or lattice. For each of the four stackings with vertical alignment of sites in two l…
