论文摘要
在先前的工作中(Li等人的Science 364,170)[1],我们提出了一个保留反对时间(APT)对称性的传热系统,并观察到对称性破裂过程中其余的运动相变。最近,有人建议(Zhao等人Arxiv:1906.08431)[2],可以使用基于Péclet和Nusselt数字(PE和NU)的缩放分析来理解系统的行为。还提出,除了对称和对称的损坏相外,相图中存在第三个方向。尽管我们感谢提出耦合,扩散和以无量纲数字的对流的贡献的建议,但在这里我们表明它们无助于预测或解释APT系统的行为。无量纲的数字没有提供有关系统的足够详细信息,无法得出结论,存在一动阶段,一个相变,以找到关键点或仅具有两个制度的正确相图。
In a previous work (Li et al. Science 364, 170) [1], we proposed a heat transfer system that preserves the anti-parity-time (APT) symmetry, and observe the rest-to-motion phase transition during the symmetry breaking. Recently, it was suggested (Zhao et al. arXiv:1906.08431) [2] that the behaviours of the system can be understood using scaling analysis based on the Péclet and Nusselt numbers (Pe and Nu). It was further proposed that there exists a third regime in the phase diagram in addition to the symmetric and symmetry broken phases. Although we appreciate the proposal to characterize the contributions of coupling, diffusion, and advection with dimensionless numbers, here we show that they do not help to predict or interpret the behaviours of the APT system. The dimensionless numbers do not provide enough details about the system to conclude that there is a motionless phase, a phase transition, to find the critical point, or to give the correct phase diagram with only two regimes.
