Evidence for Higher order topology in Bi and BiSb
Leena Aggarwal, Penghao Zhu, Taylor L. Hughes +1
Higher order topological insulators (HOTIs) are a new class of topological materials which host protected states at the corners or hinges of a crystal. HOTIs provide an intriguing…
Correlating Structural, Electronic, and Magnetic Properties of Epitaxial VSe2 Thin Films
Guannan Chen, Sean T. Howard, Aniceto B. Maghirang +9
The electronic and magnetic properties of transition metal dichalcogenides are known to be extremely sensitive to their structure. In this paper we study the effect of structure on…
Observation of linearly dispersive edge modes in a magnetic Weyl semimetal Co3Sn2S2
Sean Howard, Lin Jiao, Zhenyu Wang +5
The physical realization of Chern insulators is of fundamental and practical interest, as they are predicted to host the quantum anomalous Hall effect (QAHE) and topologically prot…
Microscopic evidence for a chiral superconducting order parameter in the heavy fermion superconductor UTe2
Lin Jiao, Sean Howard, Sheng Ran +6
Spin-triplet superconductivity is a condensate of electron pairs with spin-1 and an odd-parity wavefunction. A particularly interesting manifestation of triplet pairing is a chiral…
Searching for topological Fermi arcs via quasiparticle interference on a type-II Weyl semimetal MoTe
Davide Iaia, Guoqing Chang, Tay-Rong Chang +5
Weyl semimetals display a novel topological phase of matter where the Weyl nodes emerge in pairs of opposite chirality and can be seen as either a source or a sink of Berry curvatu…
Nanoscale Determination of the Mass Enhancement Factor in the Lightly-Doped Bulk Insulator Lead Selenide
Ilija Zeljkovic, Kane L Scipioni, Daniel Walkup +10
Bismuth chalcogenides and lead telluride/selenide alloys exhibit exceptional thermoelectric properties which could be harnessed for power generation and device applications. Since…
