Negative dynamic conductance of a quantum wire with unscreened Coulomb interaction
Bagun S. Shchamkhalova, Vladimir A. Sablikov
Dynamic conductance and time-of-flight current instability in a quantum wire connected to electron reservoirs under DC bias voltage are studied in the absence of a gate screening t…

Charged impurity scattering in two-dimensional topological insulators with Mexican-hat dispersion
Bagun S. Shchamkhalova, Vladimir A. Sablikov
Scattering by charged impurities is known to mainly determine transport properties of electrons in modern quantum materials, but it remains poorly studied for materials with Mexica…
