论文摘要
我们表明，具有反应单位概率的反应性分子自然提供了一些有趣的黑洞物理学的模拟器。短距离处的单位反应充当事件范围，当两个分子通过高部分波散射或偶极 - 偶极相互作用相互作用时，通过潜在屏障的物质波提供了单向交通。特别是，散射速率作为入射能的函数表现出与相互作用能量最大值的热分布，其方式与标量场相同的方式散布在黑洞的事件范围之外的潜在屏障。可以从KRB和其他分子实验中测得的温度依赖性的两体损耗率中提取这种热散射。
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.
