Doppler cooling of a trapped ion with feedback
反馈方法在离子阱Doppler冷却中的应用研究

Basing on the theory of quantum feedback by Steixner and his coworkers, we develop the master equation of Doppler cooling with feedback in an ion trap. The result of simulation shows the property of speedup the cooling,besides the influences of those arguments and whether we could realize it in experiment.
