Theoretical physicist Farok Miwivar studied the interaction between two sets of luminescent atoms in a quantum cavity - a quantum cavity is an optical device composed of two excellent small mirrors that can capture light in a small area for a long time.

This model and its predictions can be used for the next generation of superradiance lasers. They can be used and observed in cutting-edge cavity/waveguide quantum electrodynamics research.

One of the most stunning and unexpected phenomena in quantum optics is superradiance. It can be understood by imaging atoms as tiny antennas that emit electromagnetic radiation or light under appropriate conditions.

On the other hand, if these atoms are very close to each other, the atomic antennas will begin to communicate with each other and thus synchronize. This leads to light emission, whose intensity increases with the square of the number of atoms.

Recently, Farokh Mivehvar studied two sets of atoms, N1 and N2, where theoretically each atom has many atoms within a quantum cavity. This study was published in the journal Physical Review Letters. The atoms in each cluster are very close to each other and can produce superradiance.

Firstly, two huge antennas create a super giant antenna that can emit more superradiance. On the other hand, in the second method, due to the destructive competition between two large antennas, superradiance light emission is suppressed.

Especially, when the number of atoms in two ensembles is equal, superradiance light emission is suppressed.
Farokh Mivehvar said, "In addition, we also found that two giant antennas emit light, which is a combination of the two types mentioned earlier and has oscillation characteristics.".

In cutting-edge cavity/waveguide quantum electrodynamics experiments, the model and its predictions can be achieved and observed. The latest generation of so-called superradiance lasers may also find applications in the discovery.
