关于玻色-爱因斯坦凝聚体中量子辐射的可探测性

On the detectability of quantum radiation in Bose-Einstein condensates

Ralf Schützhold

摘要:

基于(Meta)稳原子或分子态间的双失谐喇曼跃迁和近年来发展起来的原子计数技术,提出了一种探测稀玻色-爱因斯坦凝聚体中声波的方案,其精度可达几个甚至单个声子的水平.这一方案可以开辟一系列新的应用,包括量子辐射现象的实验观察,如声波黑洞模拟中的霍金效应或宇宙粒子产生的声学模拟。PACS:03.75.Kk,04.70.Dy,42.65。

英文摘要:

Based on doubly detuned Raman transitions between (meta) stable atomic or molecular states and recently developed atom counting techniques, a detection scheme for sound waves in dilute Bose-Einstein condensates is proposed whose accuracy might reach down to the level of a few or even single phonons. This scheme could open up a new range of applications including the experimental observation of quantum radiation phenomena such as the Hawking effect in sonic black-hole analogues or the acoustic analogue of cosmological particle creation.
