Hidden wave function of twisted bilayer graphene: The flat band as a Landau level
نویسندگان
چکیده
We study the chirally symmetric continuum model (CS-CM) of twisted bilayer graphene. The equation on a flat band could be interpreted as Dirac torus in external non-abelian magnetic field. prove that existence implies wave-function has zero and vice verse. found hidden solution CS-CM pole instead zero. Our main result is basis wave functions Landau level From interpretation we show extra bands

Fractal Landau-level spectra in twisted bilayer graphene.
The Hofstadter butterfly spectrum for Landau levels in a two-dimensional periodic lattice is a rare example exhibiting fractal properties in a truly quantum system. However, the observation of this physical phenomenon in a conventional material will require a magnetic field strength several orders of magnitude larger than what can be produced in a modern laboratory. It turns out that for a spec...
متن کاملStrained bilayer graphene: Band structure topology and Landau level spectrum
We show that topology of the low-energy band structure in bilayer graphene critically depends on mechanical deformations of the crystal which may easily develop in suspended graphene flakes. We describe the Lifshitz transition that takes place in strained bilayers upon splitting the parabolic bands at intermediate energies into several Dirac cones at the energy scale of a few meV. Then, we show...
متن کاملTopological phases in the zeroth Landau level of bilayer graphene.
We analyze the phase diagram of the zeroth Landau level of bilayer graphene, taking into account the realistic effects of screening of the Coulomb interaction and strong mixing between two degenerate sublevels. We identify robust quantum Hall states at filling factors ν=-1, -4/3, -5/3, -8/5, -1/2 and discuss the nature of their ground states, collective excitations, and relation to the more fam...
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...
