Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Qiao Wang, , , | Summary: We consider the problem of spectral clustering under group fairness constraints, where samples from each sensitive group are approximately proportionally represented in each cluster. Traditional fair spectral clustering (FSC) methods consist of two consecutive stages, i.e., performing fair spectral […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Chen Ji, Xiang Zhang, Lucas Platter, , | Summary: Precision spectroscopy of hyperfine splitting (HFS) is a crucial tool for investigating the structure of nuclei and testing quantum electrodynamics (QED). However, accurate theoretical predictions are hindered by two-photon exchange (TPE) effects. We propose a novel formalism that […]
Kavli Affiliate: Birgitta Whaley | First 5 Authors: Ming Wen, Vibin Abraham, Gaurav Harsha, Avijit Shee, Birgitta Whaley | Summary: We test the performance of self-consistent GW and several representative implementations of vertex corrected G0W0 (G0W0{Gamma}). These approaches are tested on benchmark data sets covering full valence spectra (first ionization potentials and some inner valence […]

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, M. Cenk Gursoy, Senem Velipasalar, , | Summary: In this paper, we present a multi-agent deep reinforcement learning (deep RL) framework for network slicing in a dynamic environment with multiple base stations and multiple users. In particular, we propose a novel deep RL framework with […]
Kavli Affiliate: Ting Xu | First 5 Authors: Ting Xu, Zhen Wu, Huiyun Yang, Xinyu Dai, | Summary: Aspect Sentiment Triplet Extraction (ASTE) has achieved promising results while relying on sufficient annotation data in a specific domain. However, it is infeasible to annotate data for each individual domain. We propose to explore ASTE in the […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Peter Meisenheimer, Guy Moore, Shiyu Zhou, Hongrui Zhang, Xiaoxi Huang | Summary: A key challenge in antiferromagnetic spintronics is the control of spin configuration on nanometer scales applicable to solid-state technologies. Bismuth ferrite (BiFeO3) is a multiferroic material that exhibits both ferroelectricity and canted antiferromagnetism at […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Marc Vila, Joel E. Moore, , , | Summary: The interconversion between charge and spin degrees of freedom is of both fundamental and technological relevance in spintronics. While a non-equilibrium spin density and a charge current are related by the well known Rashba-Edelstein effect, here we […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Masayoshi Tomizuka, Hui Li, , | Summary: Contact-rich manipulation tasks often exhibit a large sim-to-real gap. For instance, industrial assembly tasks frequently involve tight insertions where the clearance is less than (0.1) mm and can even be negative when dealing with a deformable receptacle. This […]
