Monolayer MnBi 2 Te 4 : Atomic-scale insights into the 2D limit of an antiferromagnetic topological insulator

Wilber Alfaro Castro, Alexander LaFleur, Muxian Xu, Hengxin Tan et autres

As the first intrinsic antiferromagnetic topological insulator, ${\mathrm{MnBi}}_{2}{\mathrm{Te}}_{4}$ offers a platform for investigating topological phenomena driven by magnetism. Prior studies focused on bulk single crystals and exfoliated flakes, but the extreme two-dimensional (2D) limit remains underexplored, despite theoretical predictions of exotic behavior. …

Nontrivial Boundary-Mediated Superconducting Transport in a TRSB Topological Iron-Based Superconductor

Wenyao Liu, Gabriel Natale, Camron Farhang, Michael Geiwitz et autres

The interplay of superconductivity, band topology, and spontaneous time-reversal-symmetry breaking (TRSB) is expected to enable topological superconducting boundary states. FeTe0.55Se0.45 provides a promising single-material platform because it combines superconductivity, nontrivial band topology, and spontaneous magnetization in the superconducting state. Here we report …

Programmable, Spontaneous Superlattice Memory in a Monolayer Topological Insulator

Jian Tang, Siyuan Ding, Shuhan Ding, Jiangxu Li et autres

Memory is a foundational concept across disciplines, from neurobiology and electronics to artificial intelligence and quantum gravity. In materials, memory effects typically arise from ferroic orders, such as ferroelectricity and ferromagnetism, where information is stored in charge or spin degrees of freedom. …

Quantum Spin Hall Effects in Van der Waals Materials

Jian Tang, Siyuan Ding, Chengdong Wang, Ning Mao et autres

Abstract The quantum spin Hall (QSH) effect, first predicted in graphene by Kane and Mele in 2004, has become a key platform for exploring spin–orbit coupling, topology, and electronic interactions. Initially demonstrated in quantum wells, the field has expanded with the emergence …

Weyl-Superconductivity revealed by Edge Mode mediated Nonlocal Transport

Wenyao Liu, G. Natale, Camron Farhang, Michael Geiwitz et autres

Topological superconductivity (TSC) hosts exotic modes enabling error-free quantum computation and low-temperature spintronics. Despite preliminary evidence of edge modes, unambiguous signatures remain undetected. Here, we report the first observation of protected, non-local transport from the edge modes of the potential Weyl-superconductor \ch{FeTe_{0.55}Se_{0.45}}. …

Quantum spin Hall effects in van der Waals materials

Jian Tang, Siyuan Ding, Chengdong Wang, Ning Mao et autres

The quantum spin Hall (QSH) effect, first predicted in graphene by Kane and Mele in 2004, has emerged as a prototypical platform for exploring spin-orbit coupling, topology, and electronic interactions. Initially realized experimentally in quantum wells exhibiting characteristic QSH signatures, the field …

Graphene Multiplexed Sensor for Point-of-Need Viral Wastewater-Based Epidemiology

Michael Geiwitz, Owen Rivers Page, Tio Marello, M. Nichols et autres

Wastewater-based epidemiology (WBE) can help mitigate the spread of respiratory infections through the early detection of viruses, pathogens, and other biomarkers in human waste. The need for sample collection, shipping, and testing facilities drives up the cost of WBE and hinders its …
