Layer-dependent antiferromagnetic Chern and axion insulating states in UOTe
Sougata Mardanya, Barun Ghosh, Mengke Liu +8
Magnetic topological insulators have received significant interest due to their dissipationless edge states, which promise advances in energy-efficient electronic transport. Howeve…
Quasi-one-dimensional taco-shaped bands in large-angle twisted bilayer transition metal dichalcogenides
Giovanny Espitia, Seung Hun Lee, Calvin Kaiyu Chiu +2
Two-dimensional moiré materials offer a powerful, twist-tunable platform for engineering electronic bands and correlations, though most studies to date have focused on small twist…
Bridging the Synthesizability Gap in Perovskites by Combining Computations, Literature Data, and PU Learning
Rushik Desai, Junyeong Ahn, Alejandro Strachan +1
Among emerging energy materials, halide and chalcogenide perovskites have garnered significant attention over the last decade owing to the abundance of their constituent species, l…
Circular-polarization-selective perfect reflection from chiral superconductors
Junyeong Ahn, Ashvin Vishwanath
Integrating mirrors with magnetic components is crucial for constructing chiral optical cavities, which provide tunable platforms for time-reversal-asymmetric light-matter interact…
Symmetry tuning topological states of an axion insulator with noncollinear magnetic order
S. X. M. Riberolles, A. M. NediÄ, B. Kuthanazhi +10
Topological properties of quantum materials are intimately related to symmetry. Here, we tune the magnetic order of the axion insulator candidate EuInAs from its broken-hel…
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 fundamenta…
