Screening of the band gap in electrically biased bilayer graphene: From Hartree to Hartree-Fock
Jack N. Engdahl, Zeb E. Krix, Oleg P. Sushkov
It is well known that a direct band gap may be opened in bilayer graphene via the application of a perpendicular electric field (bias). The bias and the chemical potential are cont…
Quantum magnetic oscillations in the absence of closed electron trajectories
Z. E. Krix, O. A. Tkachenko, V. A. Tkachenko +4
Quantum magnetic oscillations in crystals are typically understood in terms of Bohr-Sommerfeld quantisation, the frequency of oscillation is given by the area of a closed electron…
Formation of artificial Fermi surfaces with a triangular superlattice on a conventional two dimensional electron gas
Daisy Q. Wang, Zeb Krix, Oleg P. Sushkov +4
In nearly free electron theory the imposition of a periodic electrostatic potential on free electrons creates the bandstructure of a material, determined by the crystal lattice spa…
Artificial electrostatic crystals: a new platform for creating correlated quantum states
Daisy Q. Wang, Zeb Krix, Olga A. Tkachenko +7
The electronic properties of solids are determined by the crystal structure and interactions between electrons, giving rise to a variety of collective phenomena including supercond…
Artificial Graphene in a Strong Magnetic Field: Bulk Current Distribution and Quantum Phase Transitions
Zeb E. Krix, Oleg P. Sushkov
We present calculations of the equilibrium current density and Chern numbers for a 2DEG in a periodic potential with infinite strip geometry and a perpendicular magnetic field. We…
