Quantifying quasiparticle chirality in a chiral topological semimetal
Jiaju Wang, Jaime Sánchez-Barriga, Amit Kumar +17
Recently, the projection of the electron's spin on its crystal momentum has been proposed as a metric to quantify electronic chirality of Bloch states in crystals, which is expecte…
Parallel spin-momentum locking in a chiral topological semimetal
Jonas A. Krieger, Samuel Stolz, Inigo Robredo +23
Spin-momentum locking in solids describes a directional relationship between the electron's spin angular momentum and its linear momentum over the entire Fermi surface. While ortho…
Spin-momentum locking from topological quantum chemistry: applications to multifold fermions
Mao Lin, Iñigo Robredo, Niels B. M. Schröter +3
In spin-orbit coupled crystals, symmetries can protect multifold degeneracies with large Chern numbers and Brillouin zone spanning topological surface states. In this work, we expl…
What's knot to like? Observation of a linked loop quantum state
Ilya Belopolski, Guoqing Chang, Tyler A. Cochran +22
Quantum phases can be classified by topological invariants, which take on discrete values capturing global information about the quantum state. Over the past decades, these invaria…
Direct observation of handedness-dependent quasiparticle interference in the two enantiomers of topological chiral semimetal PdGa
Paolo Sessi, Feng-Ren Fan, Felix Küster +16
It has recently been proposed that combining chirality with topological band theory may result in a totally new class of fermions. These particles have distinct properties: they ap…
Unusual Valence State in the Antiperovskites SrSnO and SrPbO Revealed by X-ray Photoelectron Spectroscopy
D. Huang, H. Nakamura, K. Küster +6
The class of antiperovskite compounds O ( = Ca, Sr, Ba; = Sn, Pb) has attracted interest as a candidate 3D Dirac system with topological surface states protected by cr…
Observation and control of maximal Chern numbers in a chiral topological semimetal
Niels B. M. Schröter, Samuel Stolz, Kaustuv Manna +13
Topological semimetals feature protected nodal band degeneracies characterized by a topological invariant known as the Chern number (C). Nodal band crossings with linear dispersion…
