JefiPIC: A 3-D Full Electromagnetic Particle-in-Cell Simulator Based on Jefimenko's Equations on GPU
Jiannan Chen, Jun-Jie Zhang, Xueming Li +2
This paper presents a novel 3-D full electromagnetic particle-in-cell (PIC) code called JefiPIC, which uses Jefimenko's equations as the electromagnetic (EM) field solver through a…
On the uncertainty principle of neural networks
Jun-Jie Zhang, Dong-Xiao Zhang, Jian-Nan Chen +2
In this study, we explore the inherent trade-off between accuracy and robustness in neural networks, drawing an analogy to the uncertainty principle in quantum mechanics. We propos…
Charge-dependent directed flows in heavy-ion collisions by Boltzmann-Maxwell equations
Jun-Jie Zhang, Xin-Li Sheng, Shi Pu +4
We have calculated the directed flow and charge-dependent directed flow for pions and protons in Au+Au collisions at GeV by solving the coupled…
Ideal spin hydrodynamics from Wigner function approach
Hao-Hao Peng, Jun-Jie Zhang, Xin-Li Sheng +1
Based on the Wigner function in local equilibrium, we derive hydrodynamical quantities for a system of polarized spin-1/2 particles: the particle number current density, the energy…
ZMCintegral-v5.1: Support for Multi-function Integrations on GPUs
Xiao-Yan Cao, Jun-Jie Zhang
In this new version of ZMCintegral, we have added the functionality of multi-function integrations, i.e. the ability to integrate more than different functions on GPUs. Th…
JefiGPU: Jefimenko's Equations on GPU
Jun-Jie Zhang, Jian-Nan Chen, Guo-Liang Peng +2
