Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Keiran Lewellen, Rohit Mukherjee, Haoyu Guo, Saswata Roy, Valla Fatemi | Summary: Floquet engineering is a powerful method that can be used to modify the properties of interacting many-body Hamiltonians via the application of periodic time-dependent drives. Here we consider the physics of an inductively shunted superconducting […]
Kavli Affiliate: David A. Muller | First 5 Authors: Lopa Bhatt, Abigail Y. Jiang, Eun Kyo Ko, Noah Schnitzer, Grace A. Pan | Summary: The discovery of high-temperature superconductivity in bulk La$_3$Ni$_2$O$_7$ under high hydrostatic pressure and, more recently, biaxial compression in epitaxial thin films has ignited significant interest in understanding the interplay between atomic […]
Kavli Affiliate: David A. Muller | First 5 Authors: Yidi Liu, Eun Kyo Ko, Yaoju Tarn, Lopa Bhatt, Berit H. Goodge | Summary: The discovery of superconductivity under high pressure in Ruddlesden-Popper phases of bulk nickelates has sparked great interest in stabilizing ambient pressure superconductivity in thin-film form using epitaxial strain. Recently, signs of superconductivity […]
Kavli Affiliate: David Muller | First 5 Authors: Ruben Grandia, Espen Knoop, Michael A. Hopkins, Georg Wiedebach, Jared Bishop | Summary: Legged robots have achieved impressive feats in dynamic locomotion in challenging unstructured terrain. However, in entertainment applications, the design and control of these robots face additional challenges in appealing to human audiences. This work […]
Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Yichen Qiu, Bowen Shen, Kihong Lee, Zhengchao Xia | Summary: Twisted bilayer transition metal dichalcogenide semiconductors, which support flat Chern bands with enhanced interaction effects, realize a platform for fractional Chern insulators and fractional quantum spin Hall (FQSH) insulators. A recent experiment has reported the […]

Kavli Affiliate: David A. Muller | First 5 Authors: Desheng Ma, Steven E. Zeltmann, Chenyu Zhang, Zhaslan Baraissov, Yu-Tsun Shao | Summary: Precise alignment of the electron beam is critical for successful application of scanning transmission electron microscopes (STEM) to understanding materials at atomic level. Despite the success of aberration correctors, aberration correction is still […]
Kavli Affiliate: David A. Muller | First 5 Authors: Desheng Ma, Steven E. Zeltmann, Chenyu Zhang, Zhaslan Baraissov, Yu-Tsun Shao | Summary: Aberration-corrected Scanning Transmission Electron Microscopy (STEM) has become an essential tool in understanding materials at the atomic scale. However, tuning the aberration corrector to produce a sub-{AA}ngstr"om probe is a complex and time-costly […]
Kavli Affiliate: Katja C. Nowack | First 5 Authors: Austin Kaczmarek, Andrea Capa Salinas, Stephen D. Wilson, Katja C. Nowack, | Summary: We report measurements of the local temperature-dependent penetration depth, $lambda(T)$, in the Kagome superconductors AV$_3$Sb$_5$ (A = Cs, K, Rb) using scanning superconducting quantum interference device (SQUID) microscopy. Our results suggest that the […]
