Kavli Affiliate: Joel E. Moore | First 5 Authors: Jyesta M. Adhidewata, Jyesta M. Adhidewata, , , | Summary: The excitations of fractional quantum Hall effect (FQHE) states have been largely inaccessible to experimental probes until recently. New electron scanning tunneling microscopy (STM) results from Hu et.al. (2023) show promise in detecting and identifying these […]
Kavli Affiliate: Feng Wang | First 5 Authors: Kimi Team, Kimi Team, , , | Summary: We introduce Kimi K2, a Mixture-of-Experts (MoE) large language model with 32 billion activated parameters and 1 trillion total parameters. We propose the MuonClip optimizer, which improves upon Muon with a novel QK-clip technique to address training instability while […]
Kavli Affiliate: Feng Wang | First 5 Authors: Yuhong Zhang, Yuhong Zhang, , , | Summary: Animation colorization plays a vital role in animation production, yet existing methods struggle to achieve color accuracy and temporal consistency. To address these challenges, we propose textbfAnimeColor, a novel reference-based animation colorization framework leveraging Diffusion Transformers (DiT). Our approach […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Jafar Farhadi, Jafar Farhadi, , , | Summary: We evaluate the exponentially rare fluctuations of the ionic current for a dilute electrolyte by means of macroscopic fluctuation theory. We consider the fluctuating hydrodynamics of a fluid electrolyte described by a stochastic Poisson-Nernst-Planck equation. We derive the […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Feng Wang, , , | Summary: As one of the major challenges for the conservative smoothed particle hydrodynamics (SPH) method, the zero-order consistency issue, although thought to be mitigated by the particle regularization scheme, such as the transport velocity formulation, significantly damps the flow in […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Kuo-Cheng Wu, Kuo-Cheng Wu, , , | Summary: Super-resolution (SR) advances astronomical imaging by enabling cost-effective high-resolution capture, crucial for detecting faraway celestial objects and precise structural analysis. However, existing datasets for astronomical SR (ASR) exhibit three critical limitations: flux inconsistency, object-crop setting, and insufficient data diversity, […]
Kavli Affiliate: Birgitta Whaley | First 5 Authors: Yipei Zhang, Yipei Zhang, , , | Summary: Quantum Zeno dragging enables the preparation of common eigenstates of a set of observables by frequent measurement and adiabatic-like modulation of the measurement basis. In this work, we present a deeper analysis of multi-channel Zeno dragging using generalized measurements, […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Zhou Li, Zhou Li, , , | Summary: Motivated by federated learning (FL), secure aggregation (SA) aims to securely compute, as efficiently as possible, the sum of a set of inputs distributed across many users. To understand the impact of network topology, hierarchical secure aggregation (HSA) investigated […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ziqiang CHen, Ziqiang CHen, , , | Summary: This letter investigates the robust beamforming design for a near-field secure integrated sensing and communication (ISAC) system with multiple communication users (CUs) and targets, as well as multiple eavesdroppers. Taking into account the channel uncertainty constraints, we maximize the […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Siddharth Tiwary, Siddharth Tiwary, , , | Summary: Spin chains with quenched disorder exhibit rich critical behavior, often captured by real-space renormalization group (RSRG) techniques. However, the physics of such systems in the presence of random measurements (i.e., non-Hermitian dephasing) remains largely unexplored. The interplay between […]
