TL;DR: The analysis of the vibrational excitations of the surface provides a microscopic explanation for the driving forces that lead to higher-order reconstructions, namely, p(2 x 2) and c(4x 2) structures, and provides an insight into the question of the multiplicity of periodicities that are observed on this surface, even at low temperatures.

TL;DR: In this article, the authors show that the strong coupling of domain walls to surface plasmons observed in infrared nanoimaging experiments is due to topological chiral modes confined to the walls, which leads to plasmon reflection by the domain walls.

TL;DR: In this article, the authors present a theory of these images that relates these anisotropies to the off-diagonal correlations in the single-particle density matrix, and allows one to extract these correlations from the observed images.

TL;DR: In this paper, the authors study the dc conductivity as a function of carrier density and temperature in multi-Weyl semimetals (m-WSMs), a new type of Weyl semi-metals that have linear dispersion along one symmetry direction but anisotropic nonlinear dispersion in two transverse directions with a topological charge larger than one.

TL;DR: In this article, the spin texture of tensile-strained HgTe has been shown to be locked in a 2D plane on the Fermi surface with different winding numbers on either end.
