When an ensemble of atoms coherently shares an excitation, the collective atom-field coupling may become more efficient due to interference effects. This phenomenon is known as superradiance.


Resonance energy transfer

N - donor RET rate can be up to N times greater than that for N single donors.

← Superradiant fidelity:

CP potential for atomic ensemble


Collective dipole:

← CP potential for N = 50, 100 atoms and driven atom

  • Superradiant enhancement of potential
