Gap generation and semimetal-insulator phase transition in graphene
O. V. Gamayun, E. V. Gorbar, V. P. Gusynin
The gap generation is studied in suspended clean graphene in the continuum model for quasiparticles with the Coulomb interaction. We solve the gap equation with the dynamical polar…
Energy gaps at neutrality point in bilayer graphene in a magnetic field
E. V. Gorbar, V. P. Gusynin, V. A. Miransky
Utilizing the Baym-Kadanoff formalism with the polarization function calculated in the random phase approximation, the dynamics of the quantum Hall state in bilayer graphene…
Supercritical Coulomb center and excitonic instability in graphene
O. V. Gamayun, E. V. Gorbar, V. P. Gusynin
It is well known that there are resonant states with complex energy for the supercritical Coulomb impurity in graphene. We show that opening of a quasiparticle gap decreases the im…
Chiral asymmetry of the Fermi surface in dense relativistic matter in a magnetic field
E. V. Gorbar, V. A. Miransky, I. A. Shovkovy
It is revealed that in dense relativistic matter in a magnetic field, there exists a contribution to the axial current associated with a relative shift of the longitudinal momenta…
