Abstract Bloch oscillations (BOs), an important transport phenomenon, have been studied extensively in static systems but remain mysterious in Floquet systems. Here, by harnessing notions from photonic analogy, we propose a generalization of the exis

Abstract Robust laser sources are a fundamental building block for contemporary information technologies. Originating from condensed-matter physics, the concept of topology has recently entered the realm of optics, offering fundamentally new design p

We report a simple synthesis process for a wide variety of ultrasmall nanocrystals. Simply immersing a dialysis bag containing an aqueous solution of a metal salt mixed with citric acid in a NaOH solution reservoir for 10 min, nanocrystals measuring

Inverse design of a metasurface involves searching parameters in a high‐dimensional space, which needs huge computational power. To ease the computational burden, neural network, a well‐researched computer science stream, has demonstrated its pot

We have proposed and theoretically analyzed nonmetallic broadband visible-light absorbers based on alternating SiO2/InAs thin films on SiO2 substrate. Compared with the conventional absorbers, the proposed SiO2/InAs structure can achieve excellent ab
