Energy-time uncertainty principle

Click For Summary
SUMMARY

The forum discussion centers on the energy-time uncertainty principle and its interpretations, specifically regarding its implications for quantum tunneling. Participants confirm that there are multiple interpretations of the principle, with some suggesting that it may not be applicable in serious scientific texts for explaining tunneling phenomena. The discussion highlights the distinction between popular explanations and rigorous scientific understanding, emphasizing that while the principle is often referenced in literature, its application in quantum mechanics is more complex and nuanced.

I feel there are several non-eqivalent interpretations of energy-tme uncertainty principle.It is right?And if so,what are those corrects?In particular one that sees it (the uncertainty energy-time ) as a chance of violate conservation of energy for a time sufficently small.I would be grateful if someone schow my texs or articles on this topic.Thanks.Sergio

That's right. For more details see e.g.

Thanks for the link, that paper was interesting. I searched the paper for mention of tunneling, but none were found.

It had always been my understanding that energy-time uncertainty could be used to explain some kinds of quantum tunneling. Is that correct?

I believe that energy-time uncertainty is used for explanation of tunneling only in popular books on quantum physics, not in serious scientific texts.
 
In QM tunneling can it even be said that the particle spends any real time inside the barrier? You cannot find it there.

Its an unequivocal prediction of the theory - it can be found there if you were to measure it.

Thanks
