本文用实际哈密顿量系统地讨论了Floquet本征态热化假设的违反。我们的模型是基于无无序的PXP型相互作用。通过给出波函数的显式表达式，我们精确地证明了Floquet本征态中多体疤痕态的存在性。使用潜在的物理机制，可以系统地设计具有Floquet-scar状态的各种驱动哈密顿量。
The violation of the Floquet version of eigenstate thermalization hypothesis is systematically discussed with realistic Hamiltonians. Our model is based on the PXP type interactions without disorder. We exactly prove the existence of many-body scar states in the Floquet eigenstates, by showing the explicit expressions of the wave functions. Using the underlying physical mechanism, various driven Hamiltonians with Floquet-scar states can be systematically engineered.
