Well-posedness and regularity for the fractional Navier-Stokes equations

Ning Tang

We consider the wellposedness of the fractional Navier-Stokes as a generalization of the wellposedness result in Koch-Tataru's paper. An interesting remark is that our result does…

Stability of the catenoid for the hyperbolic vanishing mean curvature equation in 4 spatial dimensions

Ning Tang

We establish the asymptotic stability of the catenoid, as a nonflat stationary solution to the hyperbolic vanishing mean curvature (HVMC) equation in Minkowski space $\mathbb{R}^{1…

Equivalence of the measures of non-Markovianty for open two-level systems

Hao-Sheng Zeng, Ning Tang, Yan-Ping Zheng +1

In order to depict the deviation of quantum time evolution in open systems from Markovian processes, different measures have been presented. We demonstrate that the measure propose…

Correlation quantum beats induced by non-Markovian effect

Hao-Sheng Zeng, Yan-Ping Zheng, Ning Tang +1

For two qubits independently coupled to their respective structured reservoirs (Lorentzian spectrum), quantum beats for entanglement and discord are found which are the result of q…

ChartWalker: Benchmarking the Cross-Chart RAG Task with Hierarchical Knowledge Graphs

Ning Tang, Chenghan Xie, Hanyang Yuan +6

Cross-Chart Retrieval-Augmented Generation (RAG) is critical for complex multi-modal analytical tasks in scientific, business, and political domains. However, existing benchmarks e…

Synthetic Acceleration Preconditioners for Parametric Radiative Transfer Equations based on Trajectory-Aware Reduced Order Models

Ning Tang, Zhichao Peng

The parametric radiative transfer equation (RTE) arises in multi-query applications, such as design optimization, inverse problems, and uncertainty quantification, which require so…
