装载玻色子原子的双阱是模拟热化和平衡现象中一些最有趣的方面的理想候选者。在这里，我们报告了一个详尽的分析动力学和稳态性质的这种系统局部接触不同的温度储层。我们证明了热化只是“偶然”发生的。我们进一步研究了双井系统动力学所隐含的非经典特征和能量通量，从而探索了其与井间非经典关联沉降有关的有限时间热力学。
A double well loaded with bosonic atoms represents an ideal candidate to simulate some of the most interesting aspects in the phenomenology of thermalisation and equilibration. Here we report an exhaustive analysis of the dynamics and steady state properties of such a system locally in contact with different temperature reservoirs. We show that thermalisation only occurs ‘accidentally’. We further examine the nonclassical features and energy fluxes implied by the dynamics of the double-well system, thus exploring its finite-time thermodynamics in relation to the settlement of nonclassical correlations between the wells.
