We present a fundamental limit to the sympathetic cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work done by the trap electric field during a long-range ion-atom...

We demonstrate resolved sideband laser cooling of a single 40Ca+ ion in a macroscopic linear radio frequency trap with a radial diagonal electrode spacing of 7 mm and an rf drive frequency of just 3.7...

Cooling a range of molecules to ultracold temperatures (<1 mK) is a difficult but important challenge in molecular physics and chemistry. Collective cavity cooling of molecules is a promising method t...

Abstract: We demonstrate loading, trapping and adiabatic cooling of polar molecules in a new type of electric trap. The trap consists of two microstructured capacitor plates with an additional perimet...

Abstract: Doppler cooling on a narrow transition is limited by the noise of single scattering events. It shows novel features, which are in sharp contrast with cooling on a broad transition, such as a...

Abstract: We investigate sub-Doppler laser cooling of bosonic potassium isotopes, whose small hyperfine splitting has so far prevented cooling below the Doppler temperature. We find instead that the c...

The prospects of sympathetic cooling of polar molecules with magnetically co-trapped alkalimetal atoms are generally considered poor due to strongly anisotropic atom-molecule interactions leading to l...
