Magnetic topological insulators have received significant interest due to their dissipationless edge states, which promise advances in energy-efficient electronic transport. Howeve…
Wavefunction-Free Approach for Predicting Nonlinear Responses in Weyl Semimetals
Mohammad Yahyavi, Ilya Belopolski, Yuanjun Jin +15
By sidestepping the intractable calculations of many-body wavefunctions, density functional theory (DFT) has revolutionized the prediction of ground states of materials. However, p…
Diverse electronic topography in a distorted kagome metal LaTi3Bi4
Anup Pradhan Sakhya, Brenden R. Ortiz, Barun Ghosh +9
Recent reports on a family of kagome metals of the form LnTi3Bi4 (Ln = Lanthanide) has stoked interest due to the combination of highly anisotropic magnetism and a rich electronic…
Topological Nature of Orbital Chern Insulators
Yueh-Ting Yao, Chia-Hung Chu, Arun Bansil +2
