Kavli Affiliate: Katja C. Nowack | First 5 Authors: Qiaochu Guo, Anthony D’Addario, Yang Cheng, Jeremy Kline, Isaiah Gray | Summary: Electrical switching of N’eel order in an antiferromagnetic insulator is desirable as a basis for memory applications. Unlike electrically-driven switching of ferromagnetic order via spin-orbit torques, electrical switching of antiferromagnetic order remains poorly understood. […]

Kavli Affiliate: Nicholas L. Abbott | First 5 Authors: Fiona Mukherjee, Anye Shi, Xin Wang, Fengqi You, Nicholas L. Abbott | Summary: Identifying and removing microplastics (MPs) from the environment is a global challenge. This study explores how the colloidal fraction of common MPs behave at aqueous interfaces of liquid crystal (LC) films. We observed […]

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Alexander Jarjour, G. M. Ferguson, Brian T. Schaefer, Menyoung Lee, Yen Lee Loh | Summary: A growing number of two-dimensional superconductors are being discovered in the family of layered van der Waals (vdW) materials. Due to small sample volume, their characterization has been largely limited to […]

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Suk Hyun Sung, Noah Schnitzer, William Millsaps, Lena F. Kourkoutis, Robert Hovden | Summary: This article introduces a training simulator for electron beam alignment using Ronchigrams. The interactive web application, www.ronchigram.com, is an advanced educational tool aimed at making scanning transmission electron microscopy (STEM) more accessible […]

Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Wenjin Zhao, Yihang Zeng, Kenji Watanabe, Takashi Taniguchi | Summary: Moir’e materials, with superlattice periodicity many times the atomic length scale, have enabled the studies of strong electronic correlations and band topology with unprecedented tunability. However, nonvolatile control of the moir’e potentials, which could allow […]

Kavli Affiliate: Jeevak Parpia | First 5 Authors: Yefan Tian, Dmytro Lotnyk, Anna Eyal, Kuang Zhang, Nikolay Zhelev | Summary: Because of the extreme purity, lack of disorder, and complex order parameter, the first-order superfluid $^3$He A-B transition is the leading model system for first order transitions in the early universe. Here we report on […]

Kavli Affiliate: David A. Muller | First 5 Authors: Nathan S. Sitaraman, Zeming Sun, Ben Francis, Ajinkya C. Hire, Thomas Oseroff | Summary: Niobium-zirconium (Nb-Zr) alloy is an old superconductor that is a promising new candidate for superconducting radio-frequency (SRF) cavity applications. Using density-functional and Eliashberg theories, we show that addition of Zr to a […]

Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Bowen Shen, Shengwei Jiang, Tingxin Li, Lizhong Li | Summary: Moir’e materials provide fertile ground for the correlated and topological quantum phenomena. Among them, the quantum anomalous Hall (QAH) effect, in which the Hall resistance is quantized even under zero magnetic field, is a direct […]

Kavli Affiliate: David Muller | First 5 Authors: Jonathan Schwartz, Chris Harris, Jacob Pietryga, Huihuo Zheng Prashant Kumar, Anastasia Visheratina | Summary: The demand for high-throughput electron tomography is rapidly increasing in biological and material sciences. However, this 3D imaging technique is computationally bottlenecked by alignment and reconstruction which runs from hours to days. We […]
