Diffuse laser cooling (DLC) provides a compact, robust, and scalable approach to generating cold-atom ensembles, offering significant potential for ground-based and spaceborne microwave atomic clocks. However, the performance of DLC systems remains limited by the weak atom-light interaction arising from their relatively low atomic density. This limitation is characterized by the optical density (OD), which quantifies the effective interaction strength between the atomic ensemble and the probe light and strongly influences the achievable signal-to-noise ratio (SNR). Although quasi-one-dimensional (quasi-1D) DLC extends the probe interaction length and improves atomic utilization, increasing the local atomic density within the interrogation region remains challenging. Here, we demonstrate a magnetically enhanced quasi-1D DLC system that simultaneously maintains the extended interaction length and increases the atomic density through a two-dimensional magnetic-field gradient.

Soon, it'll be all Starship, all the time.

Researchers at the MRC Laboratory of Medical Sciences (LMS) have developed a new way to make glowing biological reporters more accurate, allowing scientists to track gene activity in living plants over days, weeks and potentially even months and years. The approach could help researchers study how plants respond to disease, pests and environmental stress, while opening the door to similar applications in animal and human disease models.

A molecular modeling approach identifies boron- and oxygen-containing diamond defects as promising candidates for quantum technologies. The calculations focus on small atomic clusters while retaining the surrounding crystal’s influence, making sophisticated quantum chemistry more manageable. The predictions help screen candidates, but practical qubit performance still requires tests of coherence, stability and other properties. Tiny imperfections in diamond could offer new ways to store and read quantum information. The challenge is deciding which defects deserve the time and expense of experimental testing. A computational study now brings tools from molecular chemistry to that search, identifying promising boron- and oxygen-containing candidates. John Mark P. Martirez, a staff research scientist at the U. S. Department of Energy’s Princeton Plasma Physics Laboratory, reports the work in ACS Central Science. His approach concentrates demanding calculations on a small group of atoms surrounding a defect. Crucially, the model still accounts for the influence of the diamond crystal beyond that group.
