摘要
研究囚禁粒子与热库型(热辐射)驻波场的相互作用,通过外加驱动场,分析置于热库型驻波场中的囚禁粒子约化密度算符非对角元的时间演化,得到囚禁粒子在热库型驻波场中的相干特性。当外加驱动场的时间演化满足一定条件时,可保持囚禁粒子的相干性。
The coherence of trapped ion being put in a thermal radiation model standing wave field through an external controllable driving field is investigated. The time evolution properties of non-opposite angle element of trapped ion's reducible density rectangular array is discussed. Coherence properties of trapped ion is studied when the trapped ion interacts with an driving field in the thermal radiation model standing wave field. We obtain the properties of an external driving field when trapped ion's coherence is maintained.
