Competition between isotropic and strongly anisotropic terms in the impact ionization rate of narrow- and middle-gap cubic semiconductors
A. N. Afanasiev, A. A. Greshnov, G. G. Zegrya
We report on the strong anisotropy of the inter-band process of impact ionization in direct-gap cubic semiconductors with either weak or strong spin-orbit coupling at low effective…
Ballistic flow of two-dimensional electrons in a magnetic field
A. N. Afanasiev, P. S. Alekseev, A. A. Greshnov +1
In conductors with a very small density of defects, electrons at low temperatures collide predominantly with the edges of a sample. Therefore, the ballistic regime of charge and he…
Acoustic plasmons and isotropic short-range interaction in two-component electron liquids
A. N. Afanasiev
Dispersion of acoustic plasmons and isotropic Landau parameters are calculated in three- and two-dimensional two-component electron-electron and electron-hole liquids at various co…
Acoustic plasmons in type-I Weyl semimetals
A. N. Afanasiev, A. A. Greshnov, D. Svintsov
Massless chiral fermions emergent in inversion symmetry-breaking Weyl semimetals (WSMs) reside in the vicinity of multiple low symmetry nodes and thus acquire strongly anisotropic…
On the origin of hard X-ray emissions from the behind-the-limb flare on 2014 September 1
Yihong Wu, Alexis P. Rouillard, Athanasios Kouloumvakos +6
The origin of hard X-rays and gamma-rays emitted from the solar atmosphere during occulted solar flares is still debated. The hard X-ray emissions could come from flaring loop tops…
