At zero intensity, the last glimmer of the light vanishes into the atoms, and the polariton comes to a dead stop. 到了控制光强度归零之时,光的最后一丝光芒都消逝到原子里,极化声子就完全停止了。
In physics, polaritons/pəˈlærᵻtɒnz, poʊ-/ are quasiparticles resulting from strong coupling of electromagnetic waves with an electric or magnetic dipole-carrying excitation. They are an expression of the common quantum phenomenon known as level repulsion, also known as the avoided crossing principle. Polaritons describe the crossing of the dispersion of light with any interacting resonance.
