Kavli Affiliate: Peidong Yang | First 5 Authors: Jonah R. Adelman, Hugo Laurell, Lauren B. Drescher, Han K. D. Le, Peidong Yang | Summary: The narrow bandgap semiconductor elemental tellurium (Te) has a unique electronic structure due to strong spin-orbit splitting and a lack of inversion symmetry of it’s helical lattice. Using broadband extreme ultraviolet […]

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Petra Awad, Ting S. Li, Denis Erkal, Reynier F. Peletier, Kerstin Bunte | Summary: As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of these tails is […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nathan Jamieson, Aaron Smith, Meredith Neyer, Rahul Kannan, Enrico Garaldi | Summary: The growth of ionized hydrogen bubbles in the intergalactic medium around early luminous objects is a fundamental process during the Epoch of Reionization (EoR). In this study, we analyze bubble sizes and their evolution using […]
Kavli Affiliate: Ran Wang | First 5 Authors: Han Qing Yang, Jun Yan Dai, Hui Dong Li, Lijie Wu, Meng Zhen Zhang | Summary: The programmable metasurface is regarded as one of the most promising transformative technologies for next-generation wireless system applications. Due to the lack of effective perception ability of the external electromagnetic environment, […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Julie Belleville, Prachi Thureja, Harry A. Atwater, , | Summary: We introduce a conceptual framework for a lensless imaging system which employs an active metasurface as a high-frequency, continuously tunable amplitude and phase modulation aperture, coupled to a discrete single-pixel detector. Using an array factor formalism, […]
