Atomic emission rate inside a quantum resonator

الملخص EN

We present a general formalism for studying the emission rate of an atom inside a high Q-factor quantum cylindrical resonator.

The electromagnetic field structure inside such closed resonator is derived.

Then the cavity modes are quantised, allowing the positiondependent atomic emission rate to be calculated.

Depending on the circumstances, the atomic emission rate may be increased or reduced, and in extreme cases is completely suppressed.

Especially, in the quantum size system, the atomic emission rate is possible only via a few cavity modes.

The calculations are carried out for the sodium atoms immersed in an empty quantum size resonator.
