Kavli Affiliate: Ankit Disa | First 5 Authors: Jonathan B. Curtis, Ankit Disa, Michael Fechner, Andrea Cavalleri, Prineha Narang | Summary: By using intense coherent electromagnetic radiation, it may be possible to manipulate the properties of quantum materials very quickly, or even induce new and potentially useful phases that are absent in equilibrium. For instance, […]

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 […]

Kavli Affiliate: Frank W. Wise | First 5 Authors: Yuhang Wu, Demetrios N. Christodoulides, Frank W. Wise, , | Summary: Spatiotemporal mode-locking in a laser with anomalous dispersion is investigated. Mode-locked states with varying modal content can be observed, but we find it difficult to observe highly multimode states. We describe the properties of these […]

Kavli Affiliate: Dan Luo | First 5 Authors: Dan Luo, Lixin Zou, Qingyao Ai, Zhiyu Chen, Dawei Yin | Summary: Unbiased Learning to Rank~(ULTR) that learns to rank documents with biased user feedback data is a well-known challenge in information retrieval. Existing methods in unbiased learning to rank typically rely on click modeling or inverse […]

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Noah Flemens, Dylan Heberle, Jiaoyang Zheng, Devin J. Dean, Connor Davis | Summary: Parametric amplifiers have allowed breakthroughs in ultrafast, strong-field, and high-energy density laser science and are an essential tool for extending the frequency range of powerful emerging diode-pumped solid-state laser technology. However, their impact is […]
