The results show : ( 1 ) that the dynamical properties in the system depend on the degree of entanglement of the initial two identical two - level entangled atoms and the intensity of the coherent optical field, and the atomic dipole moment can be completely squeezed via choosing optimal degree of entanglement of the initial atoms in the feeblish optical field ; ( 2 ) that the quantum properties of the system also depend on the degree of entanglement of the initial two identical two - level entangled atoms and the intensity of the coherent optical field, and the radiation field can be effectively squeezed via choosing optimal degree of entanglement of the initial atoms in the fee blish optical field
( 2 )相干態光場的強度和兩原子的初始糾纏度對光場的量子特性也有很大的影響。光場的二階相干性質(聚束與反聚束)和光場的壓縮效應均與光場強度和兩原子糾纏度相關聯。在弱光場中,選擇合適的兩原子初始糾纏度,光場壓縮深度和時間可達到最大。It has been shown that whether resonant or non - resonant interaction system, the kerr effect weakens the coupling of the field - atom, shortens the cycle of quantum collapses and revivals of the atomic level occupation and makes the nonclassical correlation properties steady. kerr effects on the properties of the correlation, on the correlation intensity between the two - mode, on the photon - number distribution and on the bunching or antibunching effect of the two - mode su ( 1, 1 ) coherent states produce obviously different characters when it is changed the initial intensity of the light field. that is to say, kerr effect on the two interaction systems is accorded
數值計算結果表明:無論是共振還是非共振相互作用, kerr效應均使原子與光場的耦合減弱,原子布居的崩塌與復甦的周期縮短,光場的非經典相關的穩定性增強;在初始光場較弱和較強兩種情況下,類kerr介質對雙模su ( 1 , 1 )相干態場兩模間的相關性、相關程度以及光子的聚束與反聚束效應產生的作用均有明顯的區別,即kerr效應對系統在共振及非共振作用時的影響是一致的。The teacher must assure that the relative distance to mike is less than 0. 5 meter, so the movable scope of teacher is strictly restricted. the disadvantage of wireless mike is : the mike breaks easily and battery costs largely. the cost is high and it is difficul to manage the equipment
授課教師必須保證與話筒間的相對距離不超過0 . 5m ,教師授課時的活動范圍受到了嚴格的約束。使用無線話筒的弱點是:話筒易損壞,電池耗電量大,使用成本高,設備管理麻煩,大量使用時存在串頻干擾,同時影響教師的外觀形象。Two spherical waves and multiple spherical waves interference, and yang ' s interference experiments are simulated by using different methods. two spherical waves interference is focused on the on - plane or out - plane of the spot light source plane and the observing plane. then, we analyze how the temporal coherence of optical waves influence the contrast of the interference pattern
