$Λ$CDM and early dark energy in latent space: a data-driven parametrization of the CMB temperature power spectrum

Posted by klaurent Tokyo

Kavli Affiliate: Eiichiro Komatsu | Summary:Finding the best parametrization for cosmological models in the absence of first-principle theories is an open question. We propose a data-driven parametrization of cosmological models given by the disentangled ‘latent’ representation of a variational autoencoder (VAE) trained to compress cosmic microwave background (CMB) temperature power spectra. We consider a broad […]

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

Posted by dbos Columbia

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

Posted by klaurent Delft

Kavli Affiliate: Andrea D. Caviglia | 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 freedom, making it difficult to uniquely identify them in charge transport phenomena. Here, we present a combination […]

Superspin Renormalization and Slow Relaxation in Random Spin Systems

Posted by dbos Berkeley

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

Posted by dbos UCAS

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 […]
