Can we have a photon BE condensate? Theoretically, can graviton and gluons and all other force propagators make BE condensates?
ZapperZ said:Er... photons ARE already in a BE condensate! They are the clearest example of such a thing.
Zz.

Why does alkali nuclei need low temperature to achieve BE condensate?
A photon BEC is a state of matter in which a large number of photons, the elementary particles of light, are cooled down to extremely low temperatures and occupy the same quantum state. This results in a coherent and dense cloud of photons, exhibiting unique properties such as superfluidity and coherence.
A photon BEC is created by trapping photons in a cavity, typically made of mirrored surfaces, and cooling them to temperatures close to absolute zero. This is achieved through the use of specialized techniques such as laser cooling and evaporative cooling.
Photon BECs have the potential to be used in various fields such as quantum computing, high-precision measurements, and advanced imaging techniques. They can also be used to study fundamental physics concepts, such as the interplay between light and matter.
One of the main challenges in exploring photon BECs is achieving the extremely low temperatures required for their formation. This requires complex and precise experimental setups, as well as specialized cooling techniques. Additionally, controlling and manipulating the photons in the BEC can be difficult due to their quantum nature.
The field of photon BECs is still relatively new and ongoing research is focused on improving techniques for creating and controlling them. Scientists are also exploring potential applications and investigating the fundamental properties of these unique states of matter.
