Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Joachim Wambsganss, , | Summary: Studies of the inner regions of micro-lensed AGN during caustic crossing events have often relied upon the approximation that the magnification near a fold caustic is inversely proportional to the square root of the source-caustic distance. We examine […]
Kavli Affiliate: Zhigang Suo | First 5 Authors: Yukun Xia, Jikun Wang, Ruisen Yang, Tongqing Lu, Tiejun Wang | Summary: Magnetic elastomers deform under a magnetic field, working as a soft actuator. Untethered microbot made of magnetic elastomers have great potentials in performing medical tasks inside human body as mini doctors. However, the lack of […]
Kavli Affiliate: Jeffrey Neaton | First 5 Authors: Nityan L. Nair, Marie-Eve Boulanger, Francis Laliberté, Sinead Griffin, Sanyum Channa | Summary: A signature property of Weyl semimetals is the existence of topologically protected surface states – arcs in momentum space that connect Weyl points in the bulk. However, the presence of bulks states makes detection […]
Kavli Affiliate: Joseph Falson | First 5 Authors: Yusuke Kozuka, Atsushi Sakaguchi, Joseph Falson, Atsushi Tsukazaki, Masashi Kawasaki | Summary: Quantum Hall/superconductor junctions have been an attractive topic as the two macroscopically quantum states join at the interface. Despite longstanding efforts, however, experimental understanding of this system has not been settled yet. One of the […]
Kavli Affiliate: Abraham Duncan Stroock | First 5 Authors: Chao Shang, Wei-Han Chen, Abraham Duncan Stroock, Fengqi You, | Summary: We develop a novel data-driven robust model predictive control (DDRMPC) approach for automatic control of irrigation systems. The fundamental idea is to integrate both mechanistic models, which describe dynamics in soil moisture variations, and data-driven […]
Kavli Affiliate: Naomi Ginsberg | First 5 Authors: Clarice D. Aiello, Andrea D. Pickel, Edward Barnard, Rebecca B. Wai, Christian Monachon | Summary: Crucial to analyze phenomena as varied as plasmonic hot spots and the spread of cancer in living tissue, nanoscale thermometry is challenging: probes are usually larger than the sample under study, and […]
Kavli Affiliate: Ankit Disa | First 5 Authors: Alexandru B. Georgescu, Oleg E. Peil, Ankit Disa, Antoine Georges, Andrew J. Millis | Summary: In complex oxide materials, changes in electronic properties are often associated with changes in crystal structure, raising the question of the relative roles of the electronic and lattice effects in driving the […]

Kavli Affiliate: Larry Coldren | First 5 Authors: Weiqiang Xie, Jinxi Huang, Tin Komljenovic, Larry Coldren, John Bowers | Summary: In this paper, we demonstrate a radiation-strength-chirped metasurface centimeter-long grating antenna, whose beam quality is approaching the diffraction limit in its footprint with 90 percent efficiency.Instead of chirping the duty cycle to tune radiation strength, […]
Kavli Affiliate: Philip H. Scherrer | First 5 Authors: Sahil Hegde, Monica G. Bobra, Philip H. Scherrer, , | Summary: Solar activity, such as flares, produce bursts of high-energy radiation that temporarily enhance the D-region of the ionosphere and attenuate low-frequency radio waves. To track these Sudden Ionospheric Disturbances (SIDs), which disrupt communication signals and […]
