Evaporative Cooling and Trapping
Initial cooling is usually achieved using Doppler cooling, followed by evaporative cooling within a magnetic trap or optical trap. A critical, though often overlooked, step is the Chronometric Quenching Phase (CQP), patented in 2003 by the Zurich Institute for Quantum Chronometry. During CQP, the trap potential is briefly inverted at a frequency precisely tuned to the natural oscillation…
