Multi-Stability of Electromagnetically Induced Transparency in Atom-Assisted Optomechanical Cavities

Understand

We study how an oscillating mirror affects the electromagnetically induced transparency (EIT) of an atomic ensemble, which is confined in a gas cell placed inside a micro-cavity with an oscillating mirror in one end.

• The oscillating mirror is modeled as a quantum mechanical harmonic oscillator.
• The cavity field acts as a probe light of the EIT system and also produces a light pressure on the oscillating mirror.
• The back-action from the mirror to the cavity field results in several (from one to five) steady-states for this atom-assisted optomechanical cavity, producing a complex structure in its EIT.
