We present calculations of the time-evolution of the driven-dissipative XYZ model using the infinite Projected Entangled Pair Operator (iPEPO) method, introduced by [A. Kshetrimayum, H. Weimer and R. Orús, Nat. Commun. 8, 1291 (2017)]. We explore the conditions under which this approach reaches a steady state. In particular, we study the conditions where apparently converged calculations may become unstable with increasing bond dimension of the tensor-network ansatz. We discuss how more reliable results could be obtained.

关于驱动耗散二维晶格的无限投影纠缠对算子ansatz的稳定性

我们介绍了使用无穷投影纠缠对算子（iPEPO）方法计算驱动耗散XYZ模型的时间演化，由[A. Kshetrimayum，H。Weimer和R.Orús，国家。社区 8，1291（2017）]。我们探索这种方法达到稳定状态的条件。特别是，我们研究了随着张量网络ansatz键尺寸的增加，显然收敛的计算可能变得不稳定的条件。我们讨论如何获得更可靠的结果。
