偶极液滴中的量子关联:含时Hartree-Fock-Bogoliubov理论

Quantum correlations in dipolar droplets: Time-dependent Hartree-Fock-Bogoliubov theory

Abdelaali Boudjemaa, Nadia Guebli

摘要:

研究了量子关联对偶极量子液滴的影响。为此,我们推导出自洽的含时Hartree-Fock-Bogoliubov方程,该方程公平地描述了液滴的序参量、正常和异常量子关联的动力学。我们分析了密度剖面、临界粒子数、凝聚体的耗尽和对关联函数。我们的预测与最近的实验和量子蒙特卡罗模拟结果进行了比较,发现非常好的协议。

英文摘要:

We investigate the effects of quantum correlations on dipolar quantum droplets. To this end,we derive self-consistent time-dependent Hartree-Fock-Bogoliubov equations that fairly describe the dynamics of the order parameter, the normal, and anomalous quantum correlations of the droplet. We analyze the density profiles, the critical number of particles, the condensate depletion, and the pair correlation function. Our predictions are compared with very recent experimental and Quantum Monte-Carlo simulations results and excellent agreement is found.
