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…
Critical number of fermions in three-dimensional QED
V. P. Gusynin, P. K. Pyatkovskiy
Previous analytical studies of quantum electrodynamics in dimensions (QED3) have shown the existence of a critical number of fermions for onset of chiral symmetry breaking, t…
Screening of a charged impurity in graphene in a magnetic field
O. O. Sobol, P. K. Pyatkovskiy, E. V. Gorbar +1
The electron states in the field of a charged impurity in graphene in a magnetic field are studied numerically. It is shown that a charged impurity removes the degeneracy of Landau…
Dynamical polarization and plasmons in a two-dimensional system with merging Dirac points
P. K. Pyatkovskiy, Tapash Chakraborty
We have studied the dynamical polarization and collective excitations in an anisotropic two-dimensional system undergoing a quantum phase transition with merging of two Dirac point…
