Linear entropies of a cascade three - level atom interacting with one - mode photon field 單模光場與級聯(lián)三能級原子相互作用系統(tǒng)中熵的時間演化
It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases , the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen , make the squeezing degree deepen obviously , and lead to the additional vibration of entropy , the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase . besides , the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number , the degree of second order coherence of field , the evolution of the field entropy and the squeezing effect are also discussed )的增大,量子噪聲分別減小和增大;虛光子過程使光場的反聚束效應(yīng)增強,使光場的壓縮程度明顯加深,并引起了附加的“熵振蕩” ,這種附加“熵振蕩”的幅度將隨著光場初始平均光子數(shù)( ? )的增加而增大,隨著光場頻率和原子間耦合系數(shù)g的增大而減小。本文還研究了充滿kerr介質(zhì)腔中“耦合雙原子-單模光場”相互作用系統(tǒng)的量子動力學(xué)性質(zhì),研究了克爾效應(yīng)對場的平均光子數(shù)、二階相干度、場熵演化特性及光場壓縮效應(yīng)的影響。
