Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy

Kavli Affiliate: Stefano Fusi | Authors: Lorenzo Posani, Shuqi Wang, Samuel Muscinelli, Liam Paninski and Stefano Fusi | Summary: A long-standing debate in neuroscience concerns whether individual neurons are organized into functionally distinct populations that encode information differently (“categorical” representations [1–3]) and the implications for neural computation. Here, we systematically analyzed how cortical neurons encode […]

Imaging orbital Rashba induced charge transport anisotropy

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Eylon Persky, Xi Wang, Giacomo Sala, Thierry C. van Thiel, Edouard Lesne | Summary: Identifying orbital textures and their effects on the electronic properties of quantum materials is a critical element in developing orbitronic devices. However, orbital effects are often entangled with the spin degree of […]

The Pristine survey: XXVIII. The extremely metal-poor stream C-19 stretches over more than 100 degrees

Zhen Yuan, Tadafumi Matsuno, Tatyana Sitnova, Nicolas F. Martin, Rodrigo A. Ibata | Summary: [[{“value”:”The discovery of the most metal-poor stream, C-19, provides us with a fossil record of a stellar structure born very soon after the Big Bang. In this work, we search for new C-19 members over the whole sky by combining two […]

Superspin Renormalization and Slow Relaxation in Random Spin Systems

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 […]

Graph-Theoretic Analysis of $n$-Replica Time Evolution in the Brownian Gaussian Unitary Ensemble

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 […]

Searching for axion dark matter gegenschein of the Vela supernova remnant with FAST

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") […]
