Quantum optical cooling of nanoparticles

Physicians at the University of Vienna have developed a novel method to cool nanoparticles using quantum optics, enabling unprecedented control over particle motion in ultra-high vacuum. The approach, inspired by atomic physics, harnesses scattered light from an optical tweezer to effectively cool particles' kinetic energy.

Physicists constrain dark matter

Researchers have constrained a theoretical model of dark matter particles using data from Earth-based radio telescopes. The study found that ultralight particles interact weakly with photons, making them hard to study, but also revealed a constraint on the available models describing dark matter composition.

How black holes power plasma jets

Astronomers have discovered that particle escapees from black holes steal rotational energy through interactions with magnetic fields, resulting in high-speed plasma jets. The new simulations show two main mechanisms: the Blandford-Znajek process and a particle-boosting mechanism near the equator.

Doubly-excited electrons reach new energy states

Physicists have characterised higher energy levels reached by electrons in resonance with positronium ions, a complex three-particle system. The new model provides guidance for experimentalists to observe these resonant structures, potentially leading to breakthroughs in atomic and nuclear physics.

Balloon measurements reveal dust particle properties in free troposphere over desert

The study used balloon-borne measurements to investigate dust particles in the free troposphere over a Chinese desert region. The findings suggest that mineral particles from desert areas have a local influence and are transported long distances, with coarse-mode particles dominating the size distribution.

Getting the most out of atmospheric data analysis

A team of researchers has developed a mutual information approach to interpreting atmospheric data collected over an 18-year period, finding strong correlations between new-particle formation and water content, sulfuric acid concentration, temperature, and relative humidity.
