Kavli Affiliate: Cheng Peng | First 5 Authors: Neil Joshi, Joshua Carney, Nathanael Kuo, Homer Li, Cheng Peng | Summary: Production of photorealistic, navigable 3D site models requires a large volume of carefully collected images that are often unavailable to first responders for disaster relief or law enforcement. Real-world challenges include limited numbers of images, […]
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: Leon Balents | First 5 Authors: Nisarga Paul, Takamori Park, Jung Hoon Han, Leon Balents, | Summary: We study the gyrotropic magnetic effect (GME), the low-frequency limit of optical gyrotropy, in metals and semimetals coupled to chiral spin textures. In these systems, the chiral spin texture which lacks inversion symmetry can imprint itself […]
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: David Gross | First 5 Authors: David Gross, Paulina Goedicke, , , | Summary: A perfect tensor of order $d$ is a state of four $d$-level systems that is maximally entangled under any bipartition. These objects have attracted considerable attention in quantum information and many-body theory. Perfect tensors generalize the combinatorial notion of […]
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, […]
