Anomalous Non-Hermitian Topological Anderson Insulator
Mina Ren, Xi Shi, Haitao Jiang +3
Strong disorder drives conventional Hermitian systems into Anderson insulating states, suppressing all topological phases. Here, we unveil symmetry-protected, anomalous topological…
Magnetically tunable multi-band near-field radiative heat transfer between two graphene sheets
Lixin Ge, Ke Gong, Yuping Cang +3
Near-field radiative heat transfer (NFRHT) is strongly related with many applications such as near-field imaging, thermos-photovoltaics and thermal circuit devices. The active cont…
Transfer matrix method for optics in graphene layers
Tianrong Zhan, Xi Shi, Yunyun Dai +2
A transfer matrix method is developed for optical calculations of non-interacting graphene layers. Within the framework of this method, optical properties such as reflection, trans…
Learning Latency-Aware Orchestration for Multi-Agent Systems
Xi Shi, Mengxin Zheng, Qian Lou
The paper introduces LAMaS, a latency‑aware orchestration framework for multi‑agent systems that learns execution graphs with critical‑path credit assignment during training and us…
Learning Latency-Aware Orchestration for Parallel Multi-Agent Systems
Xi Shi, Mengxin Zheng, Qian Lou
Multi-agent systems (MAS) enable complex reasoning by coordinating multiple agents, but often incur high inference latency due to multi-step execution and repeated model invocation…
ERNIE 5.0 Technical Report
Haifeng Wang, Hua Wu, Tian Wu +432
In this report, we introduce ERNIE 5.0, a natively autoregressive foundation model desinged for unified multimodal understanding and generation across text, image, video, and audio…
Hidden in Plain Sight: Evaluation of the Deception Detection Capabilities of LLMs in Multimodal Settings
Md Messal Monem Miah, Adrita Anika, Xi Shi +1
Detecting deception in an increasingly digital world is both a critical and challenging task. In this study, we present a comprehensive evaluation of the automated deception detect…
LegalCore: A Dataset for Event Coreference Resolution in Legal Documents
Kangda Wei, Xi Shi, Jonathan Tong +5
Recognizing events and their coreferential mentions in a document is essential for understanding semantic meanings of text. The existing research on event coreference resolution is…
Tunable Casimir equilibria with phase change materials: from quantum trapping to its release
Lixin Ge, Xi Shi, Zijun Xu +1
A stable suspension of nanoscale particles due to the Casimir force is of great interest for many applications such as sensing, non-contract nano-machines. However, the suspension…
Prediction of interface states in liquid surface waves with one-dimensional modulation
Xi Shi, Yong Sun, Chunhua Xue +1
We theoretically studied the interface states of liquid surface waves propagating through the heterojunctions formed by a bottom with one-dimensional periodic undulations. Via cons…
DHGS: Decoupled Hybrid Gaussian Splatting for Driving Scene
Xi Shi, Lingli Chen, Peng Wei +4
Existing Gaussian splatting methods often fall short in achieving satisfactory novel view synthesis in driving scenes, primarily due to the absence of crafty designs and geometric…
Dynamically tunable Fano resonance in periodically asymmetric graphene nanodisk pair
Zhengren Zhang, Xiaopeng Su, Yuancheng Fan +3
We present a dynamically frequency tunable Fano resonance planar device composed of periodically asymmetric graphene nanodisk pair for the mid-infrared region. There are two kinds…
Fluctuation-induced dispersion forces on thin DNA films
Lixin Ge, Xi Shi, Binzhong Li +1
In this work, the calculation of Casimir forces across thin DNA films is carried out based on the Lifshitz theory. The variations of Casimir forces due to the DNA thicknesses, volu…
