具有超箭跃迁的碱土类金属原子开启了腔量子电动力学的新机制。这一体制的特点是临界光子数比常规系统可以达到的要小许多个数量级。我们证明了用这样的系统实现稳态超辐射是可能的。我们讨论了基本的潜在机制以及关键的实验要求。
Alkaline-earth-metal-like atoms with ultranarrow transitions open the door to a new regime of cavity quantum electrodynamics. That regime is characterized by a critical photon number that is many orders of magnitude smaller than what can be achieved in conventional systems. We show that it is possible to achieve superradiance in steady state with such systems. We discuss the basic underlying mechanisms as well as the key experimental requirements.
