2016/1/22
Simulation of the low-temperature properties of many-body systems remains one of the major challenges in theoretical 1–3 and experimental 4–6 quantum information science. We present, and demonstrate e...

We consider the possibility of adding a stage to a dilution refrigerator to provide additional cooling by “filtering out” hot atoms. Three methods are considered: (1) effusion, where holes having diam...
Fundamental Limit to Atom-Ion Sympathetic Cooling in Paul Traps

font style='font-size:12px;'>
2012/5/31
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...

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...
Doppler cooling to the Quantum limit
Doppler Quantum limit Atomic Physics single scattering events

2011/8/4
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...

2011/8/4
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...
