囚陷离子奇偶相干态的产生以及梳形崩塌与复苏现象
GENERATION OF EVEN AND ODD COHERENT STATES OF A TRAPPED ION AND COMB-LIKE QUANTUM COLLAPSE AND REVIVAL PHENOMENON
【摘要】 首先考虑囚禁在谐振子势中的二能级离子在Lamb-Dick极限下与驻波场的相互作用,利用态选择测量来产生囚陷离子的奇偶相干态.然后研究原子反转随时间的演化,发现其在一定条件下表现为梳形崩塌与复苏现象.
【Abstract】 The interaction of a two-level ion trapped in a harmonic potential with standing light wave in the Lamb - Dick limit is considered. The odd and even coherent states can be generated via stateselective measurement. Finally,we study the time evolution of population inversion and flnd that the population inversion exhibits comb-like
