Deep neural network based adaptive learning for switched systems

no code implementations11 Jul 2022 Junjie He, Zhihang Xu, Qifeng Liao

Currently, deep neural network based methods are actively developed for learning governing equations in unknown dynamic systems, but their efficiency can degenerate for switching systems, where structural changes exist at discrete time instants.

Doping isolated one-dimensional antiferro-magnetic semiconductor Vanadium tetrasulfide ($VS_4$) nanowires with carriers induces half-metallicity

no code implementations29 Jan 2021 Shuo Li, Junjie He, Petr Nachtigall, Lukas Grajciar, Federico Brivio

Our results indicate that both bulk phase and isolated $VS_4$ NWs are semiconductors with band gaps of 2. 24 and 2. 64 eV, respectively, and that they prefer the antiferromagnetic (AFM) ground state based on DFT calculations.
