Programmable, Spontaneous Superlattice Memory in a Monolayer Topological Insulator
Jian Tang, Thomas Siyuan Ding, Shuhan Ding +24
Memory is a foundational concept across disciplines, from neurobiology and electronics to artificial intelligence and quantum gravity. In materials, memory effects typically arise…
Visualization of Tunable Electronic Structure of Monolayer TaIrTe
Sandy Adhitia Ekahana, Aalok Tiwari, Souvik Sasmal +16
Monolayer TaIrTe is an ideal platform to explore the tunability of band topology where charge doping converts the quantum spin Hall insulator (QSHI) state into a dual QSHI stat…
Interaction-Driven Topological Transitions in Monolayer TaIrTe
Jiangxu Li, Jian Tang, Louis Primeau +9
Discovering materials that combine topological phenomena with correlated electron behavior is a central pursuit in quantum materials research. Monolayer TaIrTe has recently eme…
Magnetization Dependent In-plane Anomalous Hall Effect in a Low-dimensional System
I-Hsuan Kao, Ravi Kumar Bandapelli, Zhenhong Cui +17
Anomalous Hall Effect (AHE) response in magnetic systems is typically proportional to an out-of-plane magnetization component because of the restriction imposed by system symmetrie…
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…
Directionally asymmetric nonlinear optics in planar chiral MnTiO
Xinshu Zhang, Tyler Carbin, Kai Du +7
Planar chiral structures possess a two dimensional handedness that is associated with broken mirror symmetry. Such motifs span vast length scales; examples include certain pinwheel…
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…
Single crystal growth, chemical defects, magnetic and transport properties of antiferromagnetic topological insulators (GeMn)BiTe (, )
