Kavli Affiliate: Li Xin Li |Summary:In this paper, we investigate the microscopic derivation of the entropy and the holographic RG flow in 3D C-metric. We first discuss the case of a sector in BTZ (Banados-Teitelboim-Zanelli) black hole. By rescaling the Newton’s constant we recover the area law of entropy of this sector by microstate counting. […]
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 […]
