Nulling baryonic feedback in weak lensing surveys using cross-correlations with fast radio bursts

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Masui | Summary:Baryonic feedback is a leading contaminant in studying dark matter and cosmology using cosmic shear. This has meant omitting much of the data during cosmological inference, or forward-modeling the spatial distribution of gas around dark matter halos using analytical or hydrodynamical models for baryonic feedback, which introduces nuisance parameters and […]

Spectral Uniformity of Little Red Dots: A Natural Outcome of Coevolving Seed Black Holes and Nascent Starbursts

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | Summary:The birth of seeds of massive black holes (BHs) and nascent galaxies at cosmic dawn takes place in dense gaseous environments, which play a crucial role in shaping their coevolution and radiation spectra. We investigate gas accretion during the assembly of massive halos with $M_rm hgtrsim 10^10-11~M_odot$ at redshifts $zsimeq […]

Quantum oscillations between excitonic and quantum spin Hall insulators in moiré WSe2

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Zhongdong Han, Zhongdong Han, , , | Summary: Quantum spin Hall insulators (QSHIs) and excitonic insulators (EIs) are prototypical topological and correlated states of matter, respectively. The topological phase transition between the two has attracted much theoretical interest but experimental studies have been hindered by the availability […]

OverLayBench: A Benchmark for Layout-to-Image Generation with Dense Overlaps

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Bingnan Li, Bingnan Li, , , | Summary: Despite steady progress in layout-to-image generation, current methods still struggle with layouts containing significant overlap between bounding boxes. We identify two primary challenges: (1) large overlapping regions and (2) overlapping instances with minimal semantic distinction. Through both qualitative examples […]

First principles and scanning tunneling spectroscopical evidences for thermodynamically stable “on-top” sulfur divacancy in monolayer WS$_2$

Posted by klaurent Berkeley

Kavli Affiliate: Archana Raja| Summary:Chalcogen vacancies in monolayer transition metal dichalcogenides (TMDs), such as WS$_2$, play a crucial role in various applications ranging from optoelectronics and catalysis to quantum information science (QIS), making their identification and control essential. This study focuses on WS$_2$ single vacancy and vacancy pairs. Using first principles computations, we investigate their […]

Revealing Adversarial Smart Contracts through Semantic Interpretation and Uncertainty Estimation

Posted by klaurent UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Yating Liu, Yating Liu, , , | Summary: Adversarial smart contracts, mostly on EVM-compatible chains like Ethereum and BSC, are deployed as EVM bytecode to exploit vulnerable smart contracts for financial gain. Detecting such malicious contracts at the time of deployment is an important proactive strategy to […]

Consistency-Aware Parameter-Preserving Knowledge Editing Framework for Multi-Hop Question Answering

Posted by klaurent UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Lingwen Deng, Lingwen Deng, , , | Summary: Parameter-Preserving Knowledge Editing (PPKE) enables updating models with new or corrected information without retraining or parameter adjustment. Recent PPKE approaches based on knowledge graphs (KG) to extend knowledge editing (KE) capabilities to multi-hop question answering (MHQA). However, these methods […]

Assessing the operating characteristics of an ion-milled phonon-mediated quantum parity detector

Posted by klaurent Caltech

Kavli Affiliate: Sunil Golwala | Summary:Phonon sensitive superconducting qubits promise to provide sub-eV energy deposit thresholds, useful for future rare-event experiments looking for interactions from dark matter and neutrinos. We detail here engineering results from a Quantum Parity Detector (QPDs), one of a class of phonon sensitive qubits, and, as a first measurement, show that […]

A Scalable Lift-and-Project Differentiable Approach For the Maximum Cut Problem

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Ismail Alkhouri, Ismail Alkhouri, , , | Summary: We propose a scalable framework for solving the Maximum Cut (MaxCut) problem in large graphs using projected gradient ascent on quadratic objectives. Notably, while our approach is differentiable and leverages GPUs for gradient-based optimization, it is not a machine […]
