Consistent Chiral Kinetic Theory in Weyl Materials: Chiral Magnetic Plasmons
E. V. Gorbar, V. A. Miransky, I. A. Shovkovy +1
We argue that the correct definition of the electric current in the chiral kinetic theory for Weyl materials should include the Chern-Simons contribution that makes the theory cons…
Broken symmetry states in bilayer graphene in electric and in-plane magnetic fields
Junji Jia, P. K. Pyatkovskiy, E. V. Gorbar +1
Broken symmetry states in bilayer graphene in perpendicular electric and in-plane magnetic fields are studied in the presence of the dynamically screened lo…
Dirac semimetals (=Na,K,Rb) as Weyl semimetals
E. V. Gorbar, V. A. Miransky, I. A. Shovkovy +1
We demonstrate that the physical reason for the nontrivial topological properties of Dirac semimetals (A=Na,K,Rb) is connected with a discrete symmetry of the low-energy e…
Quantum oscillations as a probe of interaction effects in Weyl semimetals in a magnetic field
E. V. Gorbar, V. A. Miransky, I. A. Shovkovy +1
The Weyl semimetal surface is modeled by applying the Bogolyubov boundary conditions, in which the quasiparticles have an infinite Dirac mass outside the semimetal. For a Weyl semi…
Dynamical polarization in ABC-stacked multilayer graphene in a magnetic field
O. O. Sobol, E. V. Gorbar, V. P. Gusynin
In the continuum low energy model, we calculate the one-loop dynamical polarization functions in ABC-stacked (rhombohedral) -layer graphene in a magnetic field. Neglecting the t…
Magneto-optical and optical probes of gapped ground states of bilayer graphene
E. V. Gorbar, V. P. Gusynin, A. B. Kuzmenko +1
We study the influence of different kinds of gaps in a quasiparticle spectrum on longitudinal and transverse optical conductivities of bilayer graphene. An exact analytical express…
