Coherent phonon motions and ordered vacancy compound mediated quantum path interference in Cu-poor CuIn$_{x}$Ga$_{(1-x)}$Se$_2$ (CIGS) with attosecond transient absorption

Kavli Affiliate: Peidong Yang | First 5 Authors: Hugo Laurell, Jonah R. Adelman, Elizaveta Yakovleva, Carl Hägglund, Kostiantyn Sopiha | Summary: In this study, coherent phonon motion is observed in bandgap excited CuIn$_{x}$Ga$_{(1-x)}$Se$_2$ (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectroscopy across the Se M$_{4,5}$ absorption edge. Two frequencies of coherent phonon motion are […]

L3A: Label-Augmented Analytic Adaptation for Multi-Label Class Incremental Learning

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Run He, Jiao Chen, Di Fang, Ming Li | Summary: Class-incremental learning (CIL) enables models to learn new classes continually without forgetting previously acquired knowledge. Multi-label CIL (MLCIL) extends CIL to a real-world scenario where each sample may belong to multiple classes, introducing several challenges: […]

GPR: Empowering Generation with Graph-Pretrained Retriever

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiaochen Wang, Zongyu Wu, Yuan Zhong, Xiang Zhang, Suhang Wang | Summary: Graph retrieval-augmented generation (GRAG) places high demands on graph-specific retrievers. However, existing retrievers often rely on language models pretrained on plain text, limiting their effectiveness due to domain misalignment and structure ignorance. To address these […]

A theory for diffusion-controlled reactions within nonequilibrium steady states

Kavli Affiliate: David T. Limmer | First 5 Authors: Seokjin Moon, David T. Limmer, , , | Summary: We study diffusion-controlled processes in nonequilibrium steady states, where standard rate theory assumptions break down. Using transition path theory, we generalize the relations between reactive probability fluxes and measures of the rate of the reaction. Stochastic thermodynamics […]

Dynamical Sweet and Sour Regions in Bichromatically Driven Floquet Qubits

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: D. Dominic Briseño-Colunga, Bibek Bhandari, Debmalya Das, Long B. Nguyen, Yosep Kim | Summary: Modern superconducting and semiconducting quantum hardware use external charge and microwave flux drives to both tune and operate devices. However, each external drive is susceptible to low-frequency (e.g., $1/f$) noise that can drastically […]
