I know that the theoretical decoherence mechanism makes the density mattrix diagonal, but my question is if that happens in real life. I mean, lets take the hidrogen atom (lets work in the QM framework And not in the QFT framework in order to have multiple stationary states) And suppose that the electron is in a superposition of energy/stationary states. In this case, does in real life the electron, through the interaction with the environment, spontaneously "choose" one of those stationary states or it remains in a superposition of energy states?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks
