Magnetization ground states and phase diagrams for a nano-sized Co hollow sphere : an onion-type magnetization state
Desheng Kong, Siming Wang, Chinping Chen
The magnetization ground states (MGSs) for a nanosized Co hollow sphere, with the outer radius, R < 50 nm, have been studied numerically by micromagnetic simulation using object or…
Surface mobility of a glass-forming polymer in an ionic liquid
Xinyu Zhang, Christian Pedersen, Haoqi Zhu +6
The free surface of glassy polymers exhibits enhanced segmental dynamics compared to the bulk, forming a liquid-like layer that lowers the glass transition temperature (Tg) in nano…
Ultrafast Electron-Lattice Coupling Dynamics in VO2 and V2O3 Thin Films
Elsa Abreu, Stephanie N. Gilbert Corder, Sun Jin Yun +11
Ultrafast optical pump - optical probe and optical pump - terahertz probe spectroscopy were performed on vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) thin films over a wi…
Permissioned Blockchain for Efficient and Secure Resource Sharing in Vehicular Edge Computing
Siming Wang, Xumin Huang, Rong Yu +2
With the fast expanding scale of vehicular networks, vehicular edge computing (VEC) has emerged and attracted growing attention from both industry and academia. Parked vehicles (PV…
Quantum Squeezing Enhanced Photothermal Microscopy
Pengcheng Fu, Xiao Liu, Siming Wang +10
Label-free optical microscopy through absorption or scattering spectroscopy provides fundamental insights across biology and materials science, yet its sensitivity remains fundamen…
Electrical Breakdown in a V2O3 device at the Insulator to Metal Transition
S. Guénon, S. Scharinger, Siming Wang +4
We have measured the electrical properties of a V2O3 thin film micro bridge at the insulator metal transition (IMT). Discontinuous jumps to lower voltages in the current voltage ch…
Blockchain-based Federated Learning for Industrial Metaverses: Incentive Scheme with Optimal AoI
Jiawen Kang, Dongdong Ye, Jiangtian Nie +6
The emerging industrial metaverses realize the mapping and expanding operations of physical industry into virtual space for significantly upgrading intelligent manufacturing. The i…
Dynamic conductivity scaling in photoexcited V2O3 thin films
Elsa Abreu, Siming Wang, Gabriel Ramirez +4
Optical-pump terahertz-probe spectroscopy is used to investigate ultrafast far-infrared conductivity dynamics during the insulator-to-metal transition (IMT) in vanadium sesquioxide…
Exchange Bias Induced by the Fe3O4 Verwey transition
J. de la Venta, M. Erekhinsky, Siming Wang +3
We present a study of the exchange bias in different configurations of V2O3 thin films with ferromagnetic layers. The exchange bias is accompanied by a large vertical shift in the…
