Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Wenpeng Xing, Dezhang Kong, Changting Lin, Meng Han | Summary: Safety alignment in large language models (LLMs) is achieved through fine-tuning mechanisms that regulate neuron activations to suppress harmful content. In this work, we propose a novel approach to induce disalignment by identifying and modifying […]
Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Aoran Sun, Da Wei, Yiyu Zhang, Fangfu Ye, Rudolf Podgornik | Summary: We study an active Brownian run-and-tumble particle (ABRTP) model, that consists of an active Brownian run state during which the active velocity of the particle diffuses on the unit circle, and a tumble state during […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Chunhua Zhang, Peiyao Liu, Cheng Peng, Lian-Ping Wang, Zhaoli Guo | Summary: In this work, we present a macroscopic model for the flow of two immiscible and incompressible fluids in inhomogeneous porous medium. At the pore scale, the flow is governed by the fully Navier-Stokes equations while […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Linkang Du, Zheng Zhu, Min Chen, Zhou Su, Shouling Ji | Summary: Text-to-image models based on diffusion processes, such as DALL-E, Stable Diffusion, and Midjourney, are capable of transforming texts into detailed images and have widespread applications in art and design. As such, amateur users can easily […]
Kavli Affiliate: Gang Su | First 5 Authors: Junsen Xiang, Chuandi Zhang, Yuan Gao, Wolfang Schmidt, Karin Schmalzl | Summary: Supersolid, an exotic quantum state of matter that consists of particles forming an incompressible solid structure while simultaneously showing superfluidity of zero viscosity [1], is one of the long-standing pursuits in fundamental research [2, 3]. […]
Kavli Affiliate: Long Zhang | First 5 Authors: Peipei Song, Long Zhang, Long Lan, Weidong Chen, Dan Guo | Summary: Partially relevant video retrieval (PRVR) is a practical yet challenging task in text-to-video retrieval, where videos are untrimmed and contain much background content. The pursuit here is of both effective and efficient solutions to capture […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Pei-Yuan Cai, Hui-Ke Jin, Yi Zhou, , | Summary: We present a comprehensive study of topological phases in the SO($n$) spin chains using a combination of analytical parton construction and numerical techniques. For even $n=2l$, we identify a novel SPT$^2$ phase characterized by two distinct topological sectors, […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yishuai Wang, Siyuan Hong, Wenze Pan, Yi Zhou, Yanwu Xie | Summary: The extremely low superfluid density and unprecedented tunability of oxide interface superconductors provide an ideal platform for studying fluctuations in two-dimensional superconductors. In this work, we have fabricated a LaAlO3/KTaO3 interface superconductor patterned with a […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Yuxuan Chen, Shanshan Huang, Yunyao Cheng, Peng Chen, Zhongwen Rao | Summary: Time series classification (TSC) is an important task in time series analysis. Existing TSC methods mainly train on each single domain separately, suffering from a degradation in accuracy when the samples for training are insufficient […]
Kavli Affiliate: Bo Gu | First 5 Authors: Haidong Wang, Songhan Zhao, Lanhua Li, Bo Gu, Jing Xu | Summary: In this paper, we investigate a joint source-channel encoding (JSCE) scheme in an intelligent reflecting surface (IRS)-assisted multi-user semantic communication system. Semantic encoding not only compresses redundant information, but also enhances information orthogonality in a […]
