Unveiling a Hidden Percolation Transition in Monitored Clifford Circuits: Inroads from ZX-Calculus

Posted by February 18, 2025Cornell

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Einat Buznach, Debanjan Chowdhury, Jonathan Ruhman, , | Summary: We revisit the measurement-induced phase transition (MPT) in Clifford circuits, which are both classically simulable and exhibit critical behavior widely believed to be distinct from classical percolation theory, using ZX-calculus. We analyze the MPT in a dynamical model […]

High-Fidelity Novel View Synthesis via Splatting-Guided Diffusion

Posted by dbos February 18, 2025February 19, 2025Berkeley, This Week: Nanoscience

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Yang Zhang, Lukas Mehl, Markus Gross, Christopher Schroers | Summary: Despite recent advances in Novel View Synthesis (NVS), generating high-fidelity views from single or sparse observations remains a significant challenge. Existing splatting-based approaches often produce distorted geometry due to splatting errors. While diffusion-based methods leverage […]

LanP: Rethinking the Impact of Language Priors in Large Vision-Language Models

Posted by dbos February 17, 2025February 19, 2025Berkeley, This Week: Nanoscience

Kavli Affiliate: Xiang Zhang | First 5 Authors: Zongyu Wu, Yuwei Niu, Hongcheng Gao, Minhua Lin, Zhiwei Zhang | Summary: Large Vision-Language Models (LVLMs) have shown impressive performance in various tasks. However, LVLMs suffer from hallucination, which hinders their adoption in the real world. Existing studies emphasized that the strong language priors of LVLMs can […]

Estimation of Treatment Effects based on Kernel Matching

Posted by dbos February 16, 2025February 19, 2025Caltech, This Week: Nanoscience

Kavli Affiliate: Wei Gao | First 5 Authors: Chong Ding, Zheng Li, Hon Keung Tony Ng, Wei Gao, | Summary: The treatment effect represents the average causal impact or outcome difference between treatment and control groups. Treatment effects can be estimated through social experiments, regression models, matching estimators, and instrumental variables. In this paper, we […]

Imaging orbital Rashba induced charge transport anisotropy

Posted by dbos February 13, 2025February 19, 2025Delft, This Week: Nanoscience

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Eylon Persky, Xi Wang, Giacomo Sala, Thierry C. van Thiel, Edouard Lesne | Summary: Identifying orbital textures and their effects on the electronic properties of quantum materials is a critical element in developing orbitronic devices. However, orbital effects are often entangled with the spin degree of […]

Superspin Renormalization and Slow Relaxation in Random Spin Systems

Posted by dbos February 13, 2025February 19, 2025Berkeley, This Week: Nanoscience

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yi J. Zhao, Samuel J. Garratt, Joel E. Moore, , | Summary: We develop an excited-state real-space renormalization group (RSRG-X) formalism to describe the dynamics of conserved densities in randomly interacting spin-$frac{1}{2}$ systems. Our formalism is suitable for systems with $textrm{U}(1)$ and $mathbb{Z}_2$ symmetries, and we […]

LLM-Enhanced Multiple Instance Learning for Joint Rumor and Stance Detection with Social Context Information

Posted by dbos February 13, 2025February 19, 2025Caltech, This Week: Nanoscience

Kavli Affiliate: Wei Gao | First 5 Authors: Ruichao Yang, Jing Ma, Wei Gao, Hongzhan Lin, | Summary: The proliferation of misinformation, such as rumors on social media, has drawn significant attention, prompting various expressions of stance among users. Although rumor detection and stance detection are distinct tasks, they can complement each other. Rumors can […]
