Inverse scattering for waveguides in topological insulators
Guillaume Bal, Xixian Wang, Zhongjian Wang
This paper concerns the inverse scattering problem of a topologically non-trivial waveguide separating two-dimensional topological insulators. We consider the specific model of a D…

Wasserstein Bounds for generative diffusion models with Gaussian tail targets
Xixian Wang, Zhongjian Wang
We present an estimate of the Wasserstein distance between the data distribution and the generation of score-based generative models. The sampling complexity with respect to dimens…
