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.…
Theory of Band Gap Reduction Due to Conduction Electrons in 2D TMDs: Imaginary Frequency Formalism
Jack N. Engdahl, Harley D. Scammell, Dmitry K. Efimkin +1
Two Dimensional (2D) Transition Metal Dichalcogenides (TMDs) possess a large direct band gap which has been experimentally observed to shrink with increasing charge carrier density…
Excitons in Atomically Thin TMD in Electric and Magnetic Fields
Jack N. Engdahl, Harley D. Scammell, Dmitry K. Efimkin +1
The magnetic field dependence of photoabsorption provides direct insights into the band structure of semiconductors. It is perhaps surprising that there is a large discrepancy betw…
Anomalous magnetic flux via junction twist-angle in a triplet-superconducting transmon qubit
Sebastián Domínguez-Calderón, Harley D. Scammell
Superconducting transmon qubits with strong anharmonicity and insensitivity to offset charge are highly desirable for low-error implementation. In this work we propose a c-axis jun…
Displacement-field-tunable superconductivity in an inversion-symmetric twisted van der Waals heterostructure
Harley D. Scammell, Mathias S. Scheurer
We investigate the superconducting properties of inversion-symmetric twisted trilayer graphene by considering different parent states, including spin-singlet, triplet, and SO(4) de…
Exciton condensation in biased bilayer graphene
Harley D. Scammell, Oleg P. Sushkov
We consider suspened bilayer graphene under applied perpendicular electric bias field that is known to generate a single particle gap and a related electric polarization ${\ca…
