摘要:

一类哈密顿量,实验上可行的在量子光学的几个方面,并导致所谓的冷却加热费米以及玻色子系统已被数值分析。我们已经发现了一个很大的参数范围内的冷却加热可以观察到单独的费米子系统或组合的费米子和玻色子系统。通过分析实验要求,我们得出结论,通过加热冷却是可以实现的,特别是在囚禁离子和腔QED的背景下,从而有助于理解这种有趣的和违反直觉的效果。

英文摘要:

A class of Hamiltonians that are experimentally feasible in several contexts within quantum optics and lead to so-called cooling by heating for fermionic as well as for bosonic systems has been analyzed numerically. We have found a large range of parameters for which cooling by heating can be observed either for the fermionic system alone or for the combined fermionic and bosonic systems. Analyzing the experimental requirements, we conclude that cooling by heating is achievable with present-day technology, especially in the context of trapped-ion and cavity QED, thus contributing to the understanding of this interesting and counterintuitive effect.
