Title: Spinor Slow Light and Photonic Bandgap Properties

Abstract:
In this talk, I will report how we produced two-component or spinor slow light (SSL) and discuss a possible SSL application for engineering photonic bandgap media. The previous experiments all dealt with the single-component slow light. For the first time, we experimentally demonstrated SSL using a double-tripod atom-light coupling scheme [1]. As demonstrated in our work, SSL can be exploited in quantum memory/rotator for two-color qubits, interferometers for sensitive measurements, and high-efficiency media for nonlinear frequency conversion. Furthermore, SSL may lead to interesting physics such as spinor Bose-Einstein condensation of dark-state polaritons [2], Dirac particles [3], and photonic bandgap properties [4].
