Over the years, the continued development of laser-cooling methods has allowed more elements to be brought into states of quantum degeneracy, with each additional atomic species offering its own ...

The alternative way is to use different transitions in the antihydrogen atom for its cooling or new laser cooling schemes. Several attempts in this direction have been made. The powerful laser sources ...

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 ...

Conventional laser cooling of atoms relies on photons exciting the electrons inside the atom. When the electron falls back into the ground state, the atom spontaneously emits a photon. Since this ...

Call it the big chill. Laser cooling has tackled its biggest molecule yet, bringing the temperature of a three-atom molecule to within a thousandth of a kelvin of absolute zero for the first time.

Cooling positronium with lasers Researchers slow exotic atom to make it easier to study and explore antimatter Date: September 11, 2024 Source: University of Tokyo Summary: Most atoms are made ...

They will use the laser cooling innovation to help produce cold and dense sample of anti-atoms for precision spectroscopy and gravity measurements. For each experimental sequence, about 500 ...

Laser cooling, in which carefully arranged laser beams can reduce the momentum of an atom to the point where the it can be individually caught by a magnetic field, is an important technology for ...

An artistic illustration of the movement of an antihydrogen atom in the ALPHA magnetic trap, before (grey) and after (blue) laser cooling. The images show various lengths of the antihydrogen's track. ...

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 ...
