Dynamic, Ultra-Slow Optical-Matter Wave Analog of an Event Horizon
C. J. Zhu, Lu Deng, Edward W. Hagley, Mo-Lin Ge
We investigate theoretically the effects of a dynamically increasing medium index on optical- wave propagation in a rubidium condensate. A long pulsed pump laser coupling a D2 line transition produces a rapidly growing internally generated field. This results in a significant optical self-focusing effect and creates a dynamically growing medium index anomaly that propagates ultraslowly with the internally generated field. When a fast probe pulse injected after a delay catches up with the dynamically increasing index anomaly, it is forced to slow down and is prohibited from crossing the anomaly, thereby realizing an ultraslow optical-matter wave analog of a dynamic white-hole event horizon
