玻色-爱因斯坦凝聚体中引力波的模拟量子模拟

Analog quantum simulation of gravitational waves in a Bose-Einstein condensate

Tupac Bravo, Carlos Sabín, Ivette Fuentes

摘要:

我们展示了如何改变玻色-爱因斯坦凝聚体(BEC)的物理性质,以模拟一个有效的引力波时空。特别是,我们专注于模拟最近发现的创造粒子的真实时空扭曲盒型陷阱。我们表明,通过调制的声速的BEC,声子的经验与实验上可行的参数模拟时空波纹的影响。这些结果将为冷原子引力波天文学的实验计划提供信息。

英文摘要:

We show how to vary the physical properties of a Bose-Einstein condensate (BEC) in order to mimic an effective gravitational-wave spacetime. In particular, we focus in the simulation of the recently discovered creation of particles by real spacetime distortion in box-type traps. We show that, by modulating the speed of sound in the BEC, the phonons experience the effects of a simulated spacetime ripple with experimentally amenable parameters. These results will inform the experimental programme of gravitational wave astronomy with cold atoms.
