Pythagoras Superposition Principle for Localized Eigenstates of 2D Moiré Lattices

Zixuan Gao, Zhenli Xu, Zhiguo Yang +1

Moiré lattices are aperiodic systems formed by a superposition of two periodic lattices with a relative rotational angle. In optics, the photonic moiré lattice has many appealing p…

A Kernel-Independent Sum-of-Exponentials Method

Zixuan Gao, Jiuyang Liang, Zhenli Xu

We propose an accurate algorithm for a novel sum-of-exponentials (SOE) approximation of kernel functions, and develop a fast algorithm for convolution quadrature based on the SOE,…

A kernel-independent sum-of-Gaussians method by de la Vallée-Poussin sums

Jiuyang Liang, Zixuan Gao, Zhenli Xu

Approximation of interacting kernels by sum of Gaussians (SOG) is frequently required in many applications of scientific and engineering computing in order to construct efficient a…
