我们表明，具有单位反应概率的反应分子自然提供了一些有趣的黑洞物理模拟器。当两个分子通过高分波散射或偶极-偶极相互作用相互作用时，短距离处的单元反应充当事件视界，并为穿过势垒的物质波提供单向交通。特别是，作为入射能量的函数的散射率表现出类似热的分布附近的最大的相互作用能量以相同的方式作为一个标量场散射与黑洞的事件视界外的势垒。这种类热散射可以从KRb和其他分子的实验中测量的温度依赖的两体损失率中提取。
We show that reactive molecules with a unit probability of reaction naturally provide a simulator of some intriguing black hole physics. The unit reaction at the short distance acts as an event horizon and delivers a one-way traffic for matter waves passing through the potential barrier when two molecules interact by high partial-wave scatterings or dipole-dipole interactions. In particular, the scattering rate as a function of the incident energy exhibits a thermal-like distribution near the maximum of the interaction energy in the same manner as a scalar field scatters with the potential barrier outside the event horizon of a black hole. Such a thermal-like scattering can be extracted from the temperature-dependent two-body loss rate measured in experiments on KRb and other molecules.
