摘要：
We investigate the quantum squeezing of matter-wave solitons in atomic Bose-Einstein condensates. By calculating quantum fluctuations of the solitons via solving the Bogoliubov-de Gennes equations, we show that significant quantum squeezing can be realized for both bright and dark solitons. We also show that the squeezing efficiency of the solitons can be enhanced and manipulated by atom-atom interaction and soliton blackness. The results reported here are beneficial not only for understanding quantum property of matter-wave solitons, but also for promising applications of Bose-condensed quantum gases.
