我们证明了量子跃迁在夸克-胶子等离子体底铵态非平衡演化中的重要性。基于非相对论有效场论和开放量子系统框架，推导了彩色单重态和八重体对的密度矩阵。我们证明了单重态的量子再生对于理解底铵基态和激发态抑制的实验结果是必要的。所使用的重夸克输运系数值与最近的晶格QCD测定一致。
We demonstrate the importance of quantum jumps in the nonequilibrium evolution of bottomonium states in the quark-gluon plasma. Based on nonrelativistic effective field theory and the open quantum system framework, we evolve the density matrix of color singlet and octet pairs. We show that quantum regeneration of singlet states from octet configurations is necessary to understand experimental results for the suppression of both bottomonium ground and excited states. The values of the heavy-quarkonium transport coefficients used are consistent with recent lattice QCD determinations.
