The NANOGrav 15 yr Data Set: Chromatic Gaussian Process Noise Models for Six Pulsars

open access: yesThe Astrophysical Journal
Pulsar timing arrays (PTAs) are designed to detect low-frequency gravitational waves (GWs). GWs induce achromatic signals in PTA data, meaning that the timing delays do not depend on radio frequency.

Light‐Responsive Carbon Dots with Photochromism and Excitation‐Dependent Room Temperature Phosphorescence

open access: yesAdvanced Physics Research, EarlyView.
A light‐responsive system with photochromism and excitation‐dependent phosphorescence was constructed by microwave synthesis of nitrogen‐doped carbon dots(N‐CDs), which provides insights into the design and synthesis of CDs with multifunctional optical properties, promoting the application expansion of intelligent responsive materials in the fields of ...

Metalens‐Enabled Twisted Chromatic Dispersion

open access: yesAdvanced Physics Research, EarlyView.
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...
