Quantum limited super-localization and super-resolution of a source pair in three dimensions
Sudhakar Prasad, Zhixian Yu
A recent paper [Z. Yu and S. Prasad, "Quantum limited superresolution of an incoherent source pair in three dimensions," arXiv:1805.09227v2 [quant-ph] (2018)] considered the proble…
Quantum limited superresolution of an incoherent source pair in three dimensions
Zhixian Yu, Sudhakar Prasad
The error in estimating the separation of a pair of incoherent sources from radiation emitted by them and subsequently captured by an imager is fundamentally bounded below by the i…
3D Source Localization and Polarimetry using High Numerical Aperture Imaging with Rotating PSF
Zhixian Yu, Sudhakar Prasad
Rotating-PSF imaging via spiral phase engineering can localize point sources over large focal depths in a snapshot mode. This letter presents a full vector-field analysis of the ro…
Displacement induced electric force and natural self-oscillation of a free electron
Zhixian Yu, Liang Yu
We show that a kind of displacement induced temporary electric force of a single point charge can be derived by using Maxwell stress analysis. This force comes from the variation o…
On the existence of natural self-oscillation of a free electron
Zhixian Yu, Liang Yu
The possibility of the existence of natural self-oscillation of a free electron is suggested. This oscillation depends on the interaction of the electron with its own electromagnet…
