A research team at Singapore’s Nanyang Technological University (NTU) has successfully used a laser to cool down a semiconductor material known as Cadmium Sulfide. The results of the recently ...

Laser cooling has emerged as a transformative methodology for controlling the motion of atoms and molecules, utilising the momentum of light to reduce thermal motion at ultra‐low temperatures. This ...

The process of cooling materials to cryogenic temperatures is often expensive and messy. One successful method is laser cooling, where photons interact with the atoms in some way to dampen their ...

Cooling molecules with lasers is harder than cooling individual atoms with lasers. The very process of laser cooling, in which atoms are buffeted by thousands of photons, was thought by many to be ...

Antimatter particles are mirror versions of matter particles, with the opposite values of properties such as electric charge. But they ‘annihilate’ in a puff of energy when they encounter their ...

In a world where lasers are sci-fi's weapon of choice for melting away an enemy spaceship (sometimes even translating to the real world), researchers at the University of Washington have swum against ...

How can light be used to cool atoms and molecules? How can light be used to cool atoms and molecules? Lasers are known to burn things, fix eyes, and dance on powerpoint presentations. But they can ...

International researchers from AEgIS collaboration at CERN, including Prof Sadiq Rangwala, achieved laser cooling of Positronium atoms using an alexandrite laser system. The breakthrough paves the way ...

Slow motion: artistic illustration showing snippets of motion of an antihydrogen atom in the ALPHA magnetic trap, before and after laser cooling. The grey tracks are before cooling and the blue tracks ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. A bit over 25 years ago ago, probably late 1991 or very early 1992, ...

Need to cool something extra-fast? New research suggests that lasers might do the trick. Physicists proposed the idea of laser cooling 30 years ago, but until now, experiments had been largely ...

For the first time, scientists have created laser-cooled neutral plasma. The temperatures reached are around 50 times colder than that of deep space, with the plasma reaching -273C. Normally we think ...
