Discussion Overview
The discussion centers on the theoretical possibility of storing photons, exploring various methods and contexts in which this might be achieved. It includes considerations of experimental approaches, practical limitations, and potential applications in technology.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant questions whether it is theoretically possible to store photons, suggesting the idea of a container with perfect mirrors to keep photons bouncing inside.
- Another participant acknowledges the theoretical possibility but notes that practical resonant cavities are not perfect, leading to a significant chance of photons escaping, while still being useful for experiments.
- A different participant mentions recent research indicating that light can be temporarily trapped in crystals, which may be relevant for future computing technologies.
- Another contribution references experiments by Lena Hau's group at Harvard, which involve stopping light as a form of light storage.
- One participant introduces an alternative perspective, suggesting that while photons can be collected and their energy stored using solar panels and batteries, this does not equate to trapping photons in a preserved state.
Areas of Agreement / Disagreement
Participants express varying viewpoints on the feasibility and methods of storing photons, with no consensus reached on a definitive approach or understanding of the concept.
Contextual Notes
Limitations include the practical imperfections of resonant cavities, the dependence on specific experimental setups, and the distinction between energy storage and photon trapping.
