Stability of the non-Hermitian skin effect
Habib Ammari, Silvio Barandun, Bryn Davies +2
This paper shows that the skin effect in systems of non-Hermitian subwavelength resonators is robust with respect to random imperfections in the system. The subwavelength resonator…
Perturbed Block Toeplitz matrices and the non-Hermitian skin effect in dimer systems of subwavelength resonators
Habib Ammari, Silvio Barandun, Ping Liu
The aim of this paper is fourfold: (i) to obtain explicit formulas for the eigenpairs of perturbed tridiagonal block Toeplitz matrices; (ii) to make use of such formulas in order t…
UTSGAN: Unseen Transition Suss GAN for Transition-Aware Image-to-image Translation
Yaxin Shi, Xiaowei Zhou, Ping Liu +1
In the field of Image-to-Image (I2I) translation, ensuring consistency between input images and their translated results is a key requirement for producing high-quality and desirab…
An Operator Theory for Analyzing the Resolution of Multi-illumination Imaging Modalities
Ping Liu, Habib Ammari
By introducing a new operator theory, we provide a unified mathematical theory for general source resolution in the multi-illumination imaging problem. Our main idea is to transfor…
Super-resolution of positive near-colliding point sources
Ping Liu, Habib Ammari
In this paper, we analyze the capacity of super-resolution of one-dimensional positive sources. In particular, we consider the same setting as in [arXiv:1904.09186v2 [math.NA]] and…
A mathematical theory of resolution limits for super-resolution of positive sources
Ping Liu, Yanchen He, Habib Ammari
A priori information on the positivity of source intensities is ubiquitous in imaging fields and is also important for a multitude of super-resolution and deconvolution algorithms.…
