Incommensurate magnetic order drives singular angular magnetoresistance in a Weyl semimetal
X. Yao, P. Chen, R. Verma +15
We demonstrate that a multi- incommensurate magnetic state in the Weyl semimetal CeAlGe gives rise to singular angular magnetoresistance (SAMR), an electrical-transport…
Giant Shift Current in Electrically-Tunable Superlattice Bilayer Graphene
Nabil Atlam, Swati Chaudhary, Arpit Raj +4
Recent introduction of superlattice potentials has opened new avenues for engineering tunable electronic band structures featuring topologically nontrivial moiré-like bands. Here w…
Tunable Competing Electronic Orders in Double Quantum Spin Hall Superlattices
Yi-Chun Hung, Chen-Hsuan Hsu, Arun Bansil
Competing superconducting (SC) and density-wave orders are of key importance in generating unconventional superconductivity and emergent electronic responses. Quasi-one-dimensional…
Complex electronic topography and magnetotransport in an in-plane ferromagnetic kagome metal
Anup Pradhan Sakhya, Richa Pokharel Madhogaria, Barun Ghosh +11
The intricate interplay between flat bands, Dirac cones, and magnetism in kagome materials has recently attracted significant attention from materials scientists, particularly in c…
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…
Observation of the Axion quasiparticle in 2D MnBiTe
Jian-Xiang Qiu, Barun Ghosh, Jan Schütte-Engel +32
In 1978, Wilczek and Weinberg theoretically discovered a new boson-the Axion-which is the coherent oscillation of the field in QCD. Its existence can solve multiple fundamental…
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
Ground state topologies in quantum materials have unveiled many unique topological phases with novel Hall responses. Recently, the orbital Hall effect in insulators has suggested t…
