Error Analysis of Physics-Informed Neural Networks for Approximating Dynamic PDEs of Second Order in Time

no code implementations22 Mar 2023 Yanxia Qian, Yongchao Zhang, Yunqing Huang, Suchuan Dong

Our analyses show that, with feed-forward neural networks having two hidden layers and the $\tanh$ activation function, the PINN approximation errors for the solution field, its time derivative and its gradient field can be effectively bounded by the training loss and the number of training data points (quadrature points).

A posteriori error analysis of hybrid high-order method for the Stokes problem

no code implementations11 Mar 2021 Yongchao Zhang, Liquan Mei, Gang Wang

We present a residual-based a posteriori error estimator for the hybrid high-order (HHO) method for the Stokes model problem.

PASSAT at Future Neutrino Experiments: Hybrid Beam-Dump-Helioscope Facilities to Probe Light Axion-Like Particles

no code implementations21 Jan 2021 P. S. Bhupal Dev, Doojin Kim, Kuver Sinha, Yongchao Zhang

There are broadly three channels to probe axion-like particles (ALPs) produced in the laboratory: through their subsequent decay to Standard Model (SM) particles, their scattering with SM particles, or their subsequent conversion to photons.

Prospects of gravitational waves in the minimal left-right symmetric model

no code implementations26 Dec 2020 Mingqiu Li, Qi-Shu Yan, Yongchao Zhang, Zhijie Zhao

The left-right symmetric model (LRSM) is a well-motivated framework to restore parity and implement seesaw mechanisms for the tiny neutrino masses at or above the TeV-scale, and has a very rich phenomenology at both the high-energy and high-precision frontiers.
