我们探讨了远离平衡响应的全息超流体使用的AdS/CFT对应。建立了序参量源场量子猝灭对应的动力学相图。我们发现三个不同的制度的行为，与黑洞的准正规模式的频谱。这些对应于阻尼振荡的序参数和过阻尼的超流和正常状态的方法。三个制度的存在，其中包括一个新兴的动态温度标度，认为更普遍地发生在时间反演不变的系统，显示连续对称性破缺。
We explore the far-from-equilibrium response of a holographic superfluid using the AdS/CFT correspondence. We establish the dynamical phase diagram corresponding to quantum quenches of the order parameter source field. We find three distinct regimes of behavior that are related to the spectrum of black hole quasinormal modes. These correspond to damped oscillations of the order parameter and to overdamped approaches to the superfluid and normal states. The presence of three regimes, which includes an emergent dynamical temperature scale, is argued to occur more generally in time-reversal-invariant systems that display continuous symmetry breaking.
