Chiral, Electronically Decoupled Layers of 1T'-WS2 Topological Insulator via Neutral-Molecule Intercalation
Jiaze Xie, Fatmagül Katmer, Fang Yuan +9
Monolayer 1T'-WS2 is predicted to be a two-dimensional topological insulator, but its intrinsic electronic properties are masked by strong interlayer coupling in its metallic and s…
Atomically Sharp Internal Interface in a Chiral Weyl Semimetal Nanowire
Nitish Mathur, Fang Yuan, Guangming Cheng +7
Internal interfaces in Weyl semimetals (WSMs) are predicted to host distinct topological features that are different from the commonly studied external interfaces (crystal-to-vacuu…
Strain-tuned topological phase transition and unconventional Zeeman effect in ZrTe5 microcrystals
Apurva Gaikwad, Song Sun, Peipei Wang +4
The geometric phase (Berry phase) of an electronic wave function is the fundamental basis of the topological properties in solids. Modulating band structure provides a tuning knob…
Topological Materials Discovery from Crystal Symmetry
Benjamin J. Wieder, Barry Bradlyn, Jennifer Cano +8
Topological materials discovery has evolved at a rapid pace over the past 15 years following the identification of the first nonmagnetic topological insulators (TIs), topological c…
Quantum embedding methods for correlated excited states of point defects: Case studies and challenges
Lukas Muechler, Danis I. Badrtdinov, Alexander Hampel +3
A quantitative description of the excited electronic states of point defects and impurities is crucial for understanding materials properties, and possible applications of defects…
Band Engineering of Dirac Semimetals using Charge Density Waves
Shiming Lei, Samuel M. L. Teicher, Andreas Topp +13
New developments in the field of topological matter are often driven by materials discovery, including novel topological insulators, Dirac semimetals and Weyl semimetals. In the la…
