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 […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Joohwan Seo, Joohwan Seo, , , | Summary: This paper presents a framework for learning vision-based robotic policies for contact-rich manipulation tasks that generalize spatially across task configurations. We focus on achieving robust spatial generalization of the policy for the peg-in-hole (PiH) task trained from a small […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Shijun Yang, Shijun Yang, , , | Summary: Prompt learning facilitates the efficient adaptation of Vision-Language Models (VLMs) to various downstream tasks. However, it faces two significant challenges: (1) inadequate modeling of class embedding distributions for unseen instances, leading to suboptimal generalization on novel classes; (2) prevailing […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Duolin Wang, Duolin Wang, , , | Summary: In the past two decades, enormous efforts have been made to search for possible platforms and schemes to implement topological quantum computation (TQC). In exploring the Fu-Kane scheme of TQC based on Josephson trijunctions constructed on topological insulators, the […]
