TL;DR: This work investigates epitaxial thin films of the compound Co2MnSi in situ by ultraviolet-photoemission spectroscopy, taking advantage of a novel multi-channel spin filter and shows a highly spin polarized bulk-like surface resonance ingrained in a half metallic bulk band structure.

TL;DR: The notion of non-trivial topological winding in condensed matter systems represents a major area of present-day theoretical and experimental research as discussed by the authors, and the potential for major breakthroughs ranging from fundamental questions to applications as driven by an interdisciplinary exchange of ideas between areas in magnetism which traditionally have been pursued rather independently.

TL;DR: The anomalous quantum Hall effect is observed in edge channels of topological insulators when there is a magnetic energy gap at the Dirac point; this gap has now been observed by low-temperature photoelectron spectroscopy in Mn-doped Bi2Te3.

TL;DR: In this paper, the authors used ab initio methods to investigate electron scattering mechanisms behind differences in residual resistivity of the Cantor-Wu family of face-centered cubic disordered alloys.
