本文研究了偶极玻色量子流体。该流体经历平均场、超越平均场及三体相互作用。我们探讨了这些相互作用与偶极相互作用之间的竞争,以及由此竞争导致的碎裂现象。我们进一步研究了元激发,并注意到两种不同的色散区域,即旋子模式和调制不稳定性。我们通过计算超流分数和凝聚体分数来支持我们的观察。
英文摘要
In this article, we study the dipolar Bosonic quantum fluid. The fluid experiences mean-field, beyond mean-field, and three body interactions. We investigate their competition with dipolar interaction and fragmentation as a result of this competition. We further investigate the elementary excitations and note two distinct dispersion regimes, namely roton-mode and modulational instability. We support our observation by calculating the superfluid fraction and the condensate fraction.
