Rarely categorical and highly separable: how neural representations change along the cortical hierarchy

Posted by dbos December 23, 2025January 12, 2026Columbia

Kavli Affiliate: Stefano Fusi and Liam Paninski | 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 […]

Analytical quantification of strongly disordered discrete time crystals

Posted by klaurent December 23, 2025UCAS

Kavli Affiliate: Biao Huang | Summary:Discrete time crystals (DTCs) have emerged as a novel non-equilibrium phenomenon. Nevertheless, analytical quantification for disordered DTCs remains challenging, leaving uncertainties about their behaviors in large scale systems amid current debates on the stability of (Floquet-)many-body localization. In this work, we introduce an analytical framework to calculate the values of […]

Analytical quantification of strongly disordered discrete time crystals

Posted by klaurent December 23, 2025UCAS

Kavli Affiliate: Biao Huang | Summary:We introduce an analytical framework to calculate the values of key observables in a strongly disordered discrete time crystal (DTC) without fitting parameter. The perturbatively obtained closed-form formulae show quantitative agreement with numerical simulations of inverse participation ratios for eigenstate localization in Fock space, Edwards-Anderson parameters for spin-glass orders, mutual […]

BASS.L. Near-infrared Data Release 3: A Spectral Atlas and Characterization of AGN

Posted by klaurent December 23, 2025Peking

Kavli Affiliate: Claudio Ricci | Summary:We present an analysis of near-infrared (NIR) emission-line properties, AGN diagnostics, and circumnuclear gas dynamics for 453 hard X-ray selected (14$-$195 keV) AGN from the BAT AGN Spectroscopic Survey (BASS) NIR Data Release 3 (DR3; $langle z rangle=0.036$, $z<1.0$). This dataset is the largest compilation of rest-frame NIR spectroscopic observations […]

Squeezed States in Gravity

Posted by klaurent December 23, 2025MIT

Kavli Affiliate: Frank Wilczek | Summary:We present a general framework for the production of squeezed quantum states of the gravitational field in linearized quantum gravity. Time-dependent couplings in the quadratic part of the action generically produce squeezed states from the vacuum. Using the harmonic oscillator as an example, we describe three techniques to obtain the […]

Shear viscosity at finite magnetic field for graphene, non-relativistic and ultra-relativistic cases

Posted by klaurent December 23, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Present article has addressed finite magnetic field extension of previous work by Cho et al. (Phys. Rev. B 108, 235172, 2023) on microscopic calculation of shear viscosity for electron fluid in graphene system. Our calculation is based on the kinetic theory approach […]

On holography with ADE singularities

Posted by klaurent December 23, 2025Tokyo

Kavli Affiliate: Yuji Tachikawa | Summary:We study aspects of the AdS/CFT correspondence for $mathcalN=4$ $U(N)$ super Yang-Mills theory on $S^3/Γ$, where $Γsubset SU(2)$ is a finite subgroup, leading to an ADE singularity in the bulk AdS geometry. We show that a large vacuum degeneracy arises from the choice of gauge holonomy on $S^3/Γ$. On the […]

Highly Tunable Two-Qubit Interactions in Si/SiGe Quantum Dots by Interchanging the Roles of Qubit-Defining Gates

Posted by klaurent December 23, 2025Delft

Kavli Affiliate: Giordano Scappucci | Summary:Silicon quantum dot spin qubits have become a promising platform for scalable quantum computing because of their small size and compatibility with industrial semiconductor manufacturing processes. Although Si/SiGe heterostructures are commonly used to host spin qubits due to their high mobility and low percolation density, the SiGe spacer creates a […]

On the Effectiveness of Instruction-Tuning Local LLMs for Identifying Software Vulnerabilities

Posted by klaurent December 23, 2025February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Large Language Models (LLMs) show significant promise in automating software vulnerability analysis, a critical task given the impact of security failure of modern software systems. However, current approaches in using LLMs to automate vulnerability analysis mostly rely on using online API-based LLM […]

Lyman Continuum escaping from in-situ formed stars in a tidal bridge at z = 3

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We present an analysis of archival JWST NIRSpec IFS and HST imaging observations of the z = 3 Lyman-Continuum Emitter (LCE) candidate LACES104037. We show that a nearby galaxy, denoted LACES104037-S, has a redshift offset from the main galaxy by only $sim […]
