That decoherence can take place in the presence of energy conservation seems to be a poorly known fact. That lack of knowledge has, for example, bedevilled the discussion of the 'black hole information' problem. I present a simple model that illustrates such energy-free decoherence.
在能量守恒的情况下也可能发生退相干，这似乎是一个鲜为人知的事实。例如，这种知识的缺乏困扰了“黑洞信息”问题的讨论。我提出了一个简单的模型，说明了这种无能量退相干的情况。
