慢光孤子的再认识
Slow-light solitons revisited
摘要：
研究了慢光孤子在非线性$Λ$模型描述的原子介质中的传输。在一个适合于慢光传播的物理假设下，我们将$Λ$ -方案简化为一个简化的非线性模型，该模型也与二维光子引力有关。精确的解决方案，描述各种制度的停止慢光孤子，然后可以很容易地推导出来。
英文摘要：
We investigate propagation of slow-light solitons in atomic media described by the nonlinear $Λ$-model. Under a physical assumption, appropriate to the slow light propagation, we reduce the $Λ$-scheme to a simplified nonlinear model, which is also relevant to 2D dilatonic gravity. Exact solutions describing various regimes of stopping slow-light solitons can then be readily derived.
