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…
Spectrum of edge states in the quantum Hall phases in graphene
P. K. Pyatkovskiy, V. A. Miransky
Edge excitations of the quantum Hall state in monolayer graphene are studied within the mean-field theory with different symmetry-breaking terms. The analytical expressions f…
Edge states in bilayer graphene in a magnetic field
P. K. Pyatkovskiy
Edge states in biased bilayer graphene in a magnetic field are studied within the four-band continuum model. The analysis is done for the semi-infinite graphene plane and for the g…
