TL;DR: In this article, the first experimental observation and theoretical explication of spin splitting in topological crystalline insulator quantum wells made of Pb1-xSnxSe confined by Pb 1-yEuySe barriers on one side and by vacuum on the other is reported.

TL;DR: In this paper , the authors studied solid solutions between two isostructural Z$_2$ TIs, magnetic MnBi$-2$Te$_4$ and nonmagnetic GeBi$_x$Mn-Bi$ -2-Te$ -4$ with Z$ 2 invariants of 1;000 and 1;001, respectively.

TL;DR: In this paper, the electronic and spin structure of topological surface states across a topological quantum phase transition was investigated, and the authors found a surface band gap opening at the Dirac point of the topological surfaces, giving rise to massive fermions with nonzero spin polarization.
Absence of giant spin splitting in the two-dimensional electron liquid at the surface of SrTiO 3 (001)

TL;DR: In this paper, a spin and angle-resolved photo-emission experiments on fractured (001) oriented surfaces supporting a two-dimensional electron liquid with high carrier density show no detectable spin polarization in photocurrent.

TL;DR: In this article, it was shown that quantum corrections to the electronic conduction are dominated by the surface states for a semiconducting case, which can be analyzed by the Hikami-Larkin-Nagaoka model for two coupled surfaces in the case of strong spin-orbit interaction.
