Exciton condensation from level repulsion: application to bilayer graphene
Harley D. Scammell, Oleg P. Sushkov
Exciton condensation in semiconductors and semimetals has long been predicted but remains elusive. In a semiconductor, condensation occurs when the exciton binding energy matches t…

Zener tunnelling in biased bilayer graphene via analytic continuation of semiclassical theory
Harley Scammell, Oleg P. Sushkov
Employing a semiclassical method based on analytic continuation, we compute the electron-hole pair production rate in biased bilayer graphene subject to an in-plane electric field.…

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…
