Kavli Affiliate: Scott Small | Authors: Clara T Rehmann, Scott T Small, Peter L Ralph and Andrew D. Kern | Summary: As organisms adapt to environmental changes, natural selection modifies the frequency of non-neutral alleles. For beneficial mutations, the outcome of this process may be a selective sweep, in which an allele rapidly increases in […]
Kavli Affiliate: Li Xin Li| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Josephson diode (JD) effect found in Josephson tunnel junctions (JTJs) has attracted a great deal of attention due to its importance for developing superconducting circuitry based quantum technologies. So far, the highly desirable electrical control of the JD effect has not been […]
Kavli Affiliate: Gerbrand Ceder| Summary:Unconditional crystal structure generation with diffusion models faces challenges in identifying symmetric crystals as the unit cell size increases. We present the Crystal Host-Guided Generation (CHGGen) framework to address this challenge through conditional generation using an inpainting method, which optimizes a fraction of atomic positions within a predefined and symmetrized host […]

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Peichen Zhong, Xinzhe Dai, Bowen Deng, Gerbrand Ceder, Kristin A. Persson | Summary: We present Crystal Host-Guided Generation (CHGGen), a diffusion-based framework for crystal structure prediction. Unconditional generation with diffusion models demonstrates limited efficacy in identifying symmetric crystals as the unit cell size increases. CHGGen addresses […]
Kavli Affiliate: Feng Wang | First 5 Authors: Haoyuan Zhao, Jianxin Shi, Guanzhen Wu, Hao Fang, Yi Ching Chou | Summary: The advent of Low-Earth Orbit satellite networks (LSNs), exemplified by initiatives like emph{Starlink}, emph{OneWeb} and emph{Kuiper}, has ushered in a new era of “Internet from Space" global connectivity. Recent studies have shown that LSNs […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Wayne Zhao, Ruo Xi Yang, Aaron D. Kaplan, Kristin A. Persson, | Summary: Current infrared sensing devices are based on costly materials with relatively few viable alternatives known. To identify promising candidate materials for infrared photodetection, we have developed a high-throughput screening methodology based on high-accuracy […]
Kavli Affiliate: Changhuei Yang | Summary:Three-dimensional (3D) refractive index (RI) tomography offers label-free, quantitative volumetric imaging but faces limitations due to optical aberrations, limited resolution, and the computational complexity inherent to existing approaches. To overcome these barriers, we propose Analytic Fourier Ptychotomography (AFP), a new computational microscopy technique that analytically reconstructs aberration-free, complex-valued 3D RI […]
Kavli Affiliate: Clarence Chang | Summary:We introduce an array-scalable, magnon-based detector (MOSAIC) to search for the spin-dependent interactions of electron-coupled axion dark matter. These axions can excite single magnons in magnetic targets, such as the yttrium iron garnet (YIG) spheres used here, which are subsequently sensed by the detector. For MOSAIC, this sensing is implemented […]
