Abstract

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.

旋转bec中衰减湍流的热化Abrikosov晶格
我们研究了玻色-爱因斯坦凝聚体(BECs)中旋转湍流的长时间衰减。我们在旋转参考系中考虑Gross–Pitaevskii方程,并回顾了旋转BEC哈密顿量的不同公式。我们讨论了能量如何分解,并提出了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正则或大正则系综兼容的旋转BEC的有限温度状态的方法。最后,我们对雪茄形阱中的数值旋转BEC进行了积分。随着转速的增加,在系统动力学中发现了转变,湍流衰减的最终状态与有限温度热化状态下的Abrikosov晶格兼容。
