Research on Solid-State Nuclear Clocks Based on 229ThF4 Thin Films Academic Background Nuclear clocks, based on nuclear transitions, offer extremely high precision and stability. In recent years, nuclear clocks based on the thorium-229 (229Th) nuclear isomer transition have garnered significant attention. The 229Th nuclear isomer transition has an ...

Terahertz Field-Induced Metastable Magnetization Near Criticality in FePS₃ Academic Background In recent years, controlling the functional properties of quantum materials with light has emerged as a frontier in condensed matter physics, leading to the discovery of various light-induced phases of matter, such as superconductivity, ferroelectricity, ...

Controlling the Spectral Persistence of a Random Laser Research Background Since their theoretical proposal by Letokhov in the 1960s, Random Lasers (hereinafter referred to as RLs) have gradually become a widely researched field. A significant feature of RLs is that they do not require precisely manufactured optical cavities, which gives them consi...
