摘要:

研究了在电磁感应透明(EIT)条件下量子化光在相互作用里德伯介质中的耗散传输。光密原子介质中的里德伯阻塞物理导致了单光子之间的强耗散相互作用。高入射光子通量的制度构成了一个具有挑战性的多体耗散问题。我们实验研究的第一次详细的脉冲形状和二阶关联函数的传出字段和比较我们的数据与模拟的基础上两种新的理论方法非常适合于治疗这种多光子限制。在低入射通量,我们报告的理论和实验之间的良好协议。对于更高的输入通量,出射光的强度低于从理论预测获得的强度。我们解释这种差异,使用一个简单的唯象模型,考虑到污染物,这是近稳态的里德堡激发来自散射探测光子的再吸收。在高入射光子速率下,阻塞物理导致测量的关联函数的非常规形状。

英文摘要:

We study the dissipative propagation of quantized light in interacting Rydberg media under the conditions of electromagnetically induced transparency (EIT). Rydberg blockade physics in optically dense atomic media leads to strong dissipative interactions between single photons. The regime of high incoming photon flux constitutes a challenging many-body dissipative problem. We experimentally study in detail for the first time the pulse shapes and the second-order correlation function of the outgoing field and compare our data with simulations based on two novel theoretical approaches well-suited to treat this many-photon limit. At low incoming flux, we report good agreement between both theories and the experiment. For higher input flux, the intensity of the outgoing light is lower than that obtained from theoretical predictions. We explain this discrepancy using a simple phenomenological model taking into account pollutants, which are nearly-stationary Rydberg excitations coming from the reabsorption of scattered probe photons. At high incoming photon rates, the blockade physics results in unconventional shapes of measured correlation functions.
