A. Camacho-Guardian

AI总结:

本文提出利用玻色-爱因斯坦凝聚体中的极化激元,通过非破坏性方式探测强耦合杂质的高能普适谱,并基于精确两体关联的场论证明慢光阻尼率可揭示极化子谱的普适尾部。

摘要:

普适性是物理学中的一个基本概念,它允许描述与微观细节无关的系统性质。在这项工作中,我们展示了玻色-爱因斯坦凝聚体(BEC)中的极化激元是一个合适的平台,能够以非破坏性方式探测与BEC强耦合的杂质的高能普适谱。基于一个在精确水平上包含两体关联的场论,我们证明在适当条件下,慢光传播的阻尼率揭示了极化子谱中的高能普适尾部。

英文摘要:

Universality is a fundamental concept in physics that allows for the description of properties of systems that are independent of microscopic details. In this work, we show that polaritons in a Bose-Einstein condensate (BEC) are a suitable platform to probe in a non-demolition way the universal high-energy spectrum of an impurity strongly coupled to a BEC. Based on a field theory that includes the two-body correlations at the exact level we demonstrate that under appropriate conditions, the damping rate of slow-light propagation reveals the high-energy universal tail in the polaron spectrum.
