Efficient rotational cooling of Coulomb-crystallized molecular ions by a helium buffer gas
In combination with sympathetic cooling of translational degrees of freedom (leading to Coulomb crystallization), cooling of the rotational degrees of freedom of magnesium hydride ions using a helium buffer gas leads to temperatures in a tunable range from 60 kelvin down to about 7 kelvin for a sing...

| Zusammenfassung: | In combination with sympathetic cooling of translational degrees of freedom (leading to Coulomb crystallization), cooling of the rotational degrees of freedom of magnesium hydride ions using a helium buffer gas leads to temperatures in a tunable range from 60 kelvin down to about 7 kelvin for a single ion, the lowest such temperature so far recorded. |
