The effect of the electron-electron interaction on the Lifshitz transition density in bilayer graphene
Csaba Toke, Vladimir I. Fal'ko
We study the renormalization of the effective mass and trigonal warping of bilayer graphene by the electron-electron interaction. One consequence of such a renormalization in the l…
Theoretical study of even denominator fractions in graphene: Fermi sea versus paired states of composite fermions
Csaba Toke, Jainendra K. Jain
The physics of the state at even denominator fractional fillings of Landau levels depends on the Coulomb pseudopotentials, and produces, in different GaAs Landau levels, a composit…
Understanding the 5/2 Fractional Quantum Hall Effect without the Pfaffian Wave Function
Csaba Toke, Jainendra K. Jain
It is demonstrated that an understanding of the 5/2 fractional quantum Hall effect can be achieved within the composite fermion theory without appealing to the Pfaffian wave functi…
Fractional Quantum Hall Effect in Graphene
Csaba Toke, Paul E. Lammert, Jainendra K. Jain +1
Unlike regular electron spin, the pseudospin degeneracy of Fermi points in graphene does not couple directly to magnetic field. Therefore, graphene provides a natural vehicle to ob…
