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…
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…
Driving Viscous Hydrodynamics in Bulk Electron Flow in Graphene Using Micromagnets
Jack N. Engdahl, Aydın Cem Keser, Thomas Schmidt +1
We consider the hydrodynamic flow of an electron fluid in a channel formed in a two-dimensional electron gas (2DEG) with no-slip boundary conditions. To generate vorticity in the f…
Magnetic response of a two-dimensional viscous electron fluid
Aydin Cem Keser, Oleg Sushkov
It has been established that the Coulomb interactions can transform the electron gas into a viscous fluid. This fluid is realized in a number of platforms, including graphene and t…
Schiff moments of deformed nuclei
Oleg P. Sushkov
Stimulated by recent suggestion of Cosmic Axion Spin Precession Experiment with Eu contained compound we develop a new method for accurate calculation of Schiff moments of even-odd…
