Pressure-tunable phase transitions in atomically thin Chern insulator MnBiTe
Albin Marffy, Endre Tovari, Yu-Fei Liu +8
Topological insulators lacking time-reversal symmetry can exhibit the quantum anomalous Hall effect. Odd-layer thick MnBiTe is a promising platform due to its intrinsic mag…

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…

An antiferromagnetic diode effect in even-layered MnBi2Te4
Anyuan Gao, Shao-Wen Chen, Barun Ghosh +26
In a PN junction, the separation between positive and negative charges leads to diode transport. In the past few years, the intrinsic diode transport in noncentrosymmetric polar co…
