The physics of laser cooling isn't new-- even the Nobel for it is 20 years old-- but the possibilities opened by the development of those techniques are still unfolding and enabling exciting new ...

Collisional redistribution of radiation has been proposed as a cooling mechanism for atomic two-level systems. A group from Bonn University now reports a proof-of-principle experiment ...

Cooling semiconductors by laser light Date: January 23, 2012 Source: University of Copenhagen Summary: Researchers have combined two fields -- quantum physics and nano physics -- and this has led ...

The ALPHA experiment at CERN has recorded antihydrogen’s 1S–2S transition with unprecedented accuracy, using laser cooling to refine measurements. The technique significantly reduces data ...

Researchers at the Niels Bohr Institute have combined two worlds – quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes.

Laser cooling has already been successfully applied to diatomic molecules in 3D and triatomic molecules in 1D. Achieving 3D control over triatomic molecules is far more difficult, however, because the ...

Successful laser cooling was achieved in glasses—solids without an ordered, coherent crystal structure—by embedding rare-earth atoms in the matrix. As with gases, the excitation of the rare ...

The new paper demonstrates laser cooling of a centimeter-scale torsional oscillator from room temperature to a temperature of 10 millikelvins (1/1,000th of a kelvin) using a mirrored optical lever.

The international AEgIS (Antimatter Experiment: gravity, Interferometry, Spectroscopy) collaboration at CERN, in which Prof. Giovanni Consolati of the Department of Aerospace Science and ...
