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…
Observation of a Smoothly Tunable Dirac Point in
Sean Howard, Arjun Raghavan, Davide Iaia +9
State-of-the-art topological devices require the use topological surface states to drive electronic transport. In this study, we examine a tunable topological system, $Ge(Bi_{x}Sb_…
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…
Defect Role in the Carrier Tunable Topological Insulator (BiSb)Te Thin Films
Kane L Scipioni, Zhenyu Wang, Yulia Maximenko +3
Alloys of BiTe and SbTe ((BiSb)Te) have played an essential role in the exploration of topological surface states, allowing us to study phenomen…
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…
Imaging the evolution of metallic states in a spin-orbit interaction driven correlated iridate
Yoshinori Okada, Daniel Walkup, Hsin Lin +9
The Ruddlesden-Popper (RP) series of iridates (Srn+1IrnO3n+1) have been the subject of much recent attention due to the anticipation of emergent physics arising from the cooperativ…
One-dimensional channel for Dirac electrons in a 3D topological insulator
Yoshinori Okada, Wenwen Zhou, Chetan. Dhital +5
Topological insulators represent a new state of matter where the topological nature of the bulk bands dictates the existence of a surface state with unique properties. These materi…
Observation of novel interference patterns in Bi2-xFexTe3+d by Fourier transform scanning tunneling spectroscopy
Y. Okada, C. Dhital, Wen-Wen Zhou +8
In topological insulators (TI), strong spin-orbit coupling results in non-trivial scattering processes of the surface states, whose effects include suppressed back scattering1, 2,…
