手征孤子模型中缺乏真正的时间晶体
Lack of a genuine time crystal in a chiral soliton model
摘要：
在最近的出版物[物理。{ \bf 124}，178902] Öhberg和Wright声称，在手征孤子模型中，有可能实现真正的时间晶体，它对应于最低能量状态下不均匀概率密度的周期性演化。我们证明了这一结果是不正确的，并提出了一个解决方案，具有较低的能量与相应的概率密度，不显示任何运动。这意味着作者的结论，即真正的时间晶体可以存在于他们考虑的系统是不正确的。
英文摘要：
In a recent publication [Phys. Rev. Lett. {\bf 124}, 178902] Öhberg and Wright claim that in a chiral soliton model it is possible to realize a genuine time crystal which corresponds to a periodic evolution of an inhomogeneous probability density in the lowest energy state. We show that this result is incorrect and present a solution which possesses lower energy with the corresponding probability density that does not reveal any motion. It implies that the authors' conclusion that a genuine time crystal can exist in the system they consider is not true.
