标题： Graviton laser

摘要： 我们考虑创建一个引力子激光的可能性。 激光介质将是一个包含的超冷中子系统。 超冷中子是一个与引力场以及容器壁的声子相互作用的量子力学系统。 可以通过使用声子对系统进行泵浦来实现粒子数反转。 我们计算了引力子的自发发射速率和随后的受激发射速率。 可获得的增益与激光介质的密度和粒子数反转的比例成正比。 引力子激光的应用将是有趣的。 显示英文摘要

摘要： We consider the possibility of creating a graviton laser. The lasing medium would be a system of contained, ultra cold neutrons. Ultra cold neutrons are a quantum mechanical system that interacts with gravitational fields and with the phonons of the container walls. It is possible to create a population inversion by pumping the system using the phonons. We compute the rate of spontaneous emission of gravitons and the rate of the subsequent stimulated emission of gravitons. The gain obtainable is directly proportional to the density of the lasing medium and the fraction of the population inversion. The applications of a graviton laser would be interesting.
