Interband plasmons due to Mexican hat dispersion in two-dimensional materials with inverted bands
Vladimir A. Sablikov
Two-dimensional topological materials with Mexican-hat dispersion exhibit numerous nontrivial features, such as double-valued isoenergetic contours in k-space, strong mixing of ele…
Spin Hall effect in two-dimensional materials with inverted bands and Mexican-hat dispersion
Bagun S. Shchamkhalova, Vladimir A. Sablikov
We study the spin Hall effect in two-dimensional topological insulators with "Mexican hat" dispersion and a ring-shaped Fermi surface which are formed due to the band inversion. El…
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…
Friedel oscillations in two-dimensional materials with inverted bands and Mexican-hat dispersion
Vladimir A. Sablikov
We study Friedel oscillations (FOs) in two-dimensional topological materials with Mexican hat band dispersion, which attract great interest due to the bunch of its inherent non-tri…
Quasi-bound Electron Pairs in Two-Dimensional Materials with a Mexican-Hat Dispersion
Vladimir A. Sablikov, Aleksei A. Sukhanov
We study quasi-bound states of two electrons that arise in two-dimensional materials with a Mexican-hat dispersion (MHD) at an energy above its central maximum. The width of the re…
