摘要
计算和分析了玻色—爱因斯坦凝聚原子处于电磁诱导透明时的压缩特性。研究了参量对单模和双模压缩的影响。指出要增大单模压缩量可增大该模场的初始强度,减小两模间的相互作用强度。要增大双模压缩,可增大二模场的初始强度和两模间的相互作用。
In this paper atomic squeezing properties of Bose-Einstein Condensate in electromagnetically induced transparency are studied analytically and numerically. The dependence of single-mode squeezing and two-mode squeezing on the parameters is investigated in detail. It is found that the degree of single-mode squeezing can be enhanced by increasing the initial intensity of the field in this mode and decreasing the interaction between two modes and that of two-mode squeezing can be enhanced by increasing the initial intensity in both modes and the interaction between two modes.
