Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Dong-Mei Wang, Hai-Jun Wu, Dong-Sheng Ding, Carmelo Rosales-Guzmán | Summary: Abruptly autofocusing waves and associated ring-Airy (RA) beams are attracting increasing interest owing to their advantages in focusing abruptness and small F-number. Optical frequency conversion via parametric interactions can further expand their application areas, yet […]
Kavli Affiliate: Sunil Golwala | First 5 Authors: Junhan Kim, Sunil Golwala, James G. Bartlett, Stefania Amodeo, Nicholas Battaglia | Summary: The thermal Sunyaev-Zel’dovich (tSZ) effect is a powerful tool with the potential for constraining directly the properties of the hot gas that dominates dark matter halos because it measures pressure and thus thermal energy […]
Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Gautam Venugopalan, Koji Arai, Rana X Adhikari, , | Summary: We describe the design of optimized multilayer dielectric coatings for precision laser interferometry. By setting up an appropriate cost function and then using a global optimizer to find a minimum in the parameter space, we were […]

Kavli Affiliate: G. Ravichandran | First 5 Authors: N. R. Brodnik, S. Brach, C. M. Long, G. Ravichandran, B. Bourdin | Summary: Toughness describes the ability of a material to resist fracture or crack propagation. It is demonstrated here that fracture toughness of a material can be asymmetric, i.e., the resistance of a medium to […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Paolo Celli, Ilaria Nunzi, Andrea Calabrese, Stefano Lenci, Chiara Daraio | Summary: We show that shear waves traveling towards the surface of a half-space medium can be attenuated via buried one-dimensional arrays of resonators — here called metapiles — arranged according to sparse patterns around a site […]

Kavli Affiliate: Wei Gao | First 5 Authors: Hai-Jun Wu, Bing-Shi Yu, Zhi-Han Zhu, Wei Gao, Dong-Sheng Ding | Summary: Vectorial structured light with spatially varying amplitude, phase, and polarization is reshaping many areas of modern optics, including nonlinear optics, as diverse parametric processes can be used to explore interactions between such complex vector fields, […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Tapio Schneider, Oliver R. A. Dunbar, Jinlong Wu, Lucas Böttcher, Dmitry Burov | Summary: Testing, contact tracing, and isolation (TTI) is an epidemic management and control approach that is difficult to implement at scale. Here we demonstrate a scalable improvement to TTI that uses data assimilation (DA) […]
Kavli Affiliate: Wei Gao | First 5 Authors: Bo Ai, Wei Gao, Vinay, David Hsu, | Summary: How can a robot navigate successfully in a rich and diverse environment, indoors or outdoors, along an office corridor or a trail in the park, on the flat ground, the staircase, or the elevator, etc.? To this end, […]
