英文摘要 | Applying the direct simulation Monte Carlo(DSMC)method developed for the cold atom system, we explore the possibility of a high-efficiency sympathetic cooling process between ~(87)Rb and ~(40)K without gravitational force in an optical trap.The relation between the pre-cooling of Bosons and the sympathetic cooling efficiency is also studied.We find that the absence of gravitational force is beneficial to the process of sympathetic cooling.Furthermore, an inefficient pre-cooling process will in fact hamper the creation of Fermi degenerate gases.This suggests the advantages of sympathetic cooling in microgravity.; Supported by the National Fundamental Research Program of China,the National Natural Science Foundation of China; 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 4; 043401-1-043401-5; 31 |
