Resolving Two Distinct Thermal X-ray Components in A compound Solar Flare
Zhenjun Zhou, Rui Liu, Jianqing Sun +6
X-ray emission provides the most direct diagnostics of the energy-release process in solar flares. Occasionally, a superhot X-ray source is found to be above hot flare loops of ~10…
The Smoothing Proximal Gradient Algorithm with Extrapolation for the Relaxation of Regularization Problem
Jie Zhang, Xinmin Yang, Gaoxi Li +1
In this paper, we consider the exact continuous relaxation model of regularization problem which was given by Bian and Chen (SIAM J. Numer. Anal 58(1): 858-883, 2020) and pro…
Comparison of Helium Abundance between ICMEs and Solar Wind near 1 AU
Hongqiang Song, Xin Cheng, Leping Li +2
The Helium abundance, defined as , is 8.5 in the photosphere and seldom exceeds 5 in fast solar wind. Previous statistics have demonstrated tha…
Design and realization of Ohmic and Schottky interfaces for oxide electronics
Jie Zhang, Yun-Yi Pai, Jason Lapano +8
Understanding band alignment and charge transfer at complex oxide interfaces is critical to tailoring and utilizing their diverse functionality. Towards this goal, we design and ex…
MGC: A Complex-Valued Graph Convolutional Network for Directed Graphs
Jie Zhang, Bo Hui, Po-Wei Harn +2
Recent advancements in Graph Neural Networks have led to state-of-the-art performance on graph representation learning. However, the majority of existing works process directed gra…
Experimental and Numerical Verification of Anomalous Screening Theory in Granular Matter
Chandana Mondal, Michael Moshe, Itamar Procaccia +3
The concept of mechanical screening is widely applied in solid-state systems. Examples include nucleation of defects in crystalline materials, scars and pleats in curved crystals,…
Self-regulated growth of candidate topological superconducting parkerite by molecular beam epitaxy
Jason Lapano, Yun-Yi Pai, Alessandro Mazza +17
Ternary chalcogenides such as the parkerites and shandites are a broad class of materials exhibiting rich diversity of transport and magnetic behavior as well as an array of topolo…
The Inhomogeneity of Composition along the Magnetic Cloud Axis
Hongqiang Song, Qiang Hu, Xin Cheng +6
It is generally accepted that CMEs result from eruptions of magnetic flux ropes, which are dubbed as magnetic clouds in interplanetary space. The composition (including the ionic c…
Semi-Dirac and Weyl Fermions in Transition Metal Oxides
Narayan Mohanta, Jong Mok Ok, Jie Zhang +4
We show that a class of compounds with 4/ crystalline symmetry hosts three-dimensional semi-Dirac fermions. Unlike the known two-dimensional semi-Dirac points, the degenera…
Flat Band Induced Negative Magnetoresistance in Multi-Orbital Kagome Metal
Jie Zhang, T. Yilmaz, J. W. R. Meier +14
Electronic flat band systems are a fertile platform to host correlation-induced quantum phenomena such as unconventional superconductivity, magnetism and topological orders. While…
Contact force measurements and local anisotropy in ellipses and disks
Yinqiao Wang, Jin Shang, Yujie Wang +1
Experimental measurements of contact forces are limited to spheres and disks in three and two dimensions, making the evaluation of the shape effect and universality of force distri…
Experimental evidence of detailed balance in granular systems
Xulai Sun, Yinqiao Wang, Yujie Wang +2
The principle of detailed balance (DB) states that every kinetic transition in a system with many micro-states, , is balanced, on average, with the opposite transition, $μ_i\lef…
Critical behaviors of jamming in cyclically sheared frictional hard granular particles
Aile Sun, Yinqiao Wang, Yangrui Chen +5
In stark contrast to the jamming of frictionless hard-sphere (hard-disk if in two dimensions) packings, the critical jamming of frictional packings is much more elusive and still u…
Spin and polarization effects on the nonlinear Breit-Wheeler pair production in laser-plasma interaction
Huai-Hang Song, Wei-Min Wang, Yan-Fei Li +5
The spin effect of electrons/positrons (/) and polarization effect of photons are investigated in the interaction of two counter-propagating linearly polarized 10-PW-…
