Kavli Affiliate: Joel E. Moore | First 5 Authors: Yi J. Zhao, Samuel J. Garratt, Joel E. Moore, , | Summary: We develop an excited-state real-space renormalization group (RSRG-X) formalism to describe the dynamics of conserved densities in randomly interacting spin-$frac{1}{2}$ systems. Our formalism is suitable for systems with $textrm{U}(1)$ and $mathbb{Z}_2$ symmetries, and we […]
Kavli Affiliate: Kejia Lee | First 5 Authors: R. Nicolas Caballero, Heng Xu, Kejia Lee, Siyuan Chen, Yanjun Guo | Summary: We derive the gravitational-wave (GW) strain upper limits from resolvable supermassive black-hole binaries using the data from the Five-hundred-meter Aperture Spherical radio Telescope (FAST), in the context of the Chinese Pulsar Timing Array project. […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Tingfei Li, Cheng Peng, Jianghui Yu, , | Summary: In this paper, we investigate the $n$-replica time evolution operator $mathcal{U}_n(t)equiv e^{mathcal{L}_nt} $ for the Brownian Gaussian Unitary Ensemble (BGUE) using a graph-theoretic approach. We examine the moments of the generating operator $mathcal{L}_n$, which governs the Euclidean time […]
Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Wenxiu Yang, Yitian Sun, Yougang Wang, Katelin Schutz, Yichao Li | Summary: Axions are one of the leading dark matter candidates. If we are embedded in a Milky Way dark matter halo comprised of axions, their stimulated decay would enable us to observe a counterimage (“axion gegenschein") […]
Kavli Affiliate: Wei Gao | First 5 Authors: Ruichao Yang, Jing Ma, Wei Gao, Hongzhan Lin, | Summary: The proliferation of misinformation, such as rumors on social media, has drawn significant attention, prompting various expressions of stance among users. Although rumor detection and stance detection are distinct tasks, they can complement each other. Rumors can […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Matilde Lopes Abreu, Michael S. Turner, , , | Summary: The first year results of DESI provide evidence that dark energy may not be quantum vacuum energy ($Lambda$). If true, this would be an extraordinary development in the 25-year quest to understand cosmic acceleration. The best-fit […]
Kavli Affiliate: Michael McDonald | First 5 Authors: Michael Reefe, Michael McDonald, Marios Chatzikos, Jerome Seebeck, Richard Mushotzky | Summary: In the centers of many galaxy clusters, the hot ($sim$10$^7$ K) intracluster medium (ICM) can become dense enough that it should cool on short timescales. However, the low measured star formation rates in massive central […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Birgit Speh, , , | Summary: We present a new approach to symmetry breaking for pairs of real forms of $(GL(n, mathbb{C}), GL(n-1, mathbb{C}))$. While translation functors are a useful tool for studying a family of representations of a single reductive group $G$, when applied […]
Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Constantin Payerne, Zhuowen Zhang, Michel Aguena, Céline Combet, Thibault Guillemin | Summary: Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, weak gravitational lensing has proven to be a powerful tool to constrain the cluster mass-richness relation. This work is […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Wen-Hao Jiang, Cheng Peng, Yun-Song Piao, , | Summary: Double holography has been proved to be a powerful method in comprehending the spacetime entanglement. In this paper we investigate the doubly holographic construction in ${mathrm{dS_{2}} }$ spacetime. We find that in this model there exists a new […]
