摘要翻译：
用泛函积分方法研究了二能级系统热库对单粒子动力学的影响。我们发现，在低温下，在亚欧姆区域内，由于粒子-储层相互作用产生的有效势，粒子在长时间内变得{}“动态”局域化。这种行为不同于一般谐振子浴的行为，与耗散过程的非马尔可夫性质有根本联系。

英文摘要：
Using the functional-integral method, we investigate the effect of a two-level systems thermal reservoir on the single particle dynamics. We find that at low temperatures, within the sub-ohmic regime, the particle becomes {}``dynamically'' localized at long times due to an effective potential generated by the particle-reservoir interaction. This behavior is different from the one obtained for the usual bath of harmonic oscillators and is fundamentally related with the non-Markovian character of the dissipative process.
