Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Songfu Cai, Vincent K. N. Lau, , | Summary: This paper studies a sequential task offloading problem for a multiuser mobile edge computing (MEC) system. We consider a dynamic optimization approach, which embraces wireless channel fluctuations and random deep neural network (DNN) task arrivals over […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Hebai Chen, Hao Yang, Rui Zhang, Xiang Zhang, | Summary: Characterizing existence or not of periodic orbit is a classical problem and it has both theoretical importance and many real applications. Here, several new criterions on nonexistence of periodic orbits of the planar dynamical system $dot x=y,~dot […]
Kavli Affiliate: Feng Wang | First 5 Authors: Haomin Sun, Hui Deng, Feng Wang, Ying Mei, Tingting Xu | Summary: The rapid development of new generation radio interferometers such as the Square Kilometer Array (SKA) has opened up unprecedented opportunities for astronomical research. However, anthropogenic Radio Frequency Interference (RFI) from communication technologies and other human […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Yan-Qi Wang, Roman Rausch, Christoph Karrasch, Joel E. Moore, | Summary: A strongly interacting plasma of linearly dispersing electron and hole excitations in two spatial dimensions (2D), also known as a Dirac fluid, can be captured by relativistic hydrodynamics and shares many universal features with other […]
Kavli Affiliate: Feng Wang | First 5 Authors: Jixiang Yang, Guorui Chen, Tianyi Han, Qihang Zhang, Ya-Hui Zhang | Summary: ABC-stacked trilayer graphene/hBN moir’e superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. We report spectroscopy measurements of dual-gated TLG/hBN using Fourier transformed infrared photocurrent spectroscopy. We observed a strong optical transition between […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Xiang Zhang, Suhang Wang, , | Summary: Edges in real-world graphs are typically formed by a variety of factors and carry diverse relation semantics. For example, connections in a social network could indicate friendship, being colleagues, or living in the same neighborhood. However, these latent […]
Kavli Affiliate: Feng Wang | First 5 Authors: Qing-Wen Deng, Feng Wang, Hui Deng, Ying Mei, Jing Li | Summary: The Square Kilometre Array (SKA) is the largest radio interferometer under construction in the world. Its immense amount of visibility data poses a considerable challenge to the subsequent processing by the science data processor (SDP). […]
Kavli Affiliate: Feng Wang | First 5 Authors: Yi Chen, Wen-Yu He, Wei Ruan, Jinwoong Hwang, Shujie Tang | Summary: Quantum spin liquids (QSLs) are highly entangled, disordered magnetic states that arise in frustrated Mott insulators and host exotic fractional excitations such as spinons and chargons. Despite being charge insulators some QSLs are predicted to […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Stephen E. Gant, Jonah B. Haber, Marina R. Filip, Francisca Sagredo, Dahvyd Wing | Summary: The dependence of ab initio many-body perturbation theory within the $GW$ approximation on the eigensystem used in calculating quasiparticle corrections limits this method’s predictive power. Here, we investigate the accuracy of […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Jimmy-Xuan Shen, Haoming Howard Li, Ann C. Rutt, Matthew K. Horton, Kristin A. Persson | Summary: We present a graph-theoretic analysis framework for ion migration in solid-state materials. The nodes of the graph are the metastable sites of the cation and the edges are discrete migration […]
