论文摘要
我们研究了Bose-Einstein冷凝物（BEC）中旋转湍流的长期衰减。我们在旋转的参考框架中考虑了毛皮杆菌方程，并回顾了旋转BEC的哈密顿量的不同配方。我们讨论如何分解能量，并提出一种产生不平衡初始条件的方法。我们还提出了一种生成与规范或大规范合奏兼容的旋转BEC的有限温度状态。最后，我们将数值旋转的BEC整合在雪茄形陷阱中。随着旋转速率的增加，在系统动力学中发现了过渡，并且在有限温度的热层化状态下，湍流流量与Abrikosov晶格的最终状态。
We study the long-time decay of rotating turbulence in Bose-Einstein condensates (BECs). We consider the Gross-Pitaevskii equation in a rotating frame of reference, and review different formulations for the Hamiltonian of a rotating BEC. We discuss how the energy can be decomposed, and present a method to generate out-of-equilibrium initial conditions. We also present a method to generate finite-temperature states of rotating BECs compatible with the Canonical or the Grand canonical ensembles. Finally, we integrate numerically rotating BECs in cigar-shaped traps. A transition is found in the system dynamics as the rotation rate is increased, with a final state of the decay of the turbulent flow compatible with an Abrikosov lattice in a finite-temperature thermalized state.
