弱耦合玻色-爱因斯坦凝聚体中的相扩散动力学

Phase-diffusion dynamics in weakly coupled Bose-Einstein condensates

Erez Boukobza, Maya Chuchem, Doron Cohen, Amichay Vardi

摘要:

利用双模玻色-哈伯德模型的半经典图象,研究了弱耦合玻色-爱因斯坦凝聚体之间碰撞相扩散的相敏性.当弱耦合允许时,在Josephson-Fock跃迁区实现零相对相位锁定,而$π$相对相位仅锁定在Rabi-Josephson点。我们的解析半经典估计与数值结果吻合得很好。

英文摘要:

We study the phase-sensitivity of collisional phase-diffusion between weakly coupled Bose-Einstein condensates, using a semiclassical picture of the two-mode Bose-Hubbard model. When weak-coupling is allowed, zero relative phase locking is attained in the Josephson-Fock transition regime, whereas a $π$ relative phase is only locked in Rabi-Josephson point. Our analytic semiclassical estimates agree well with the numerical results.
