I can accept that.
But it is not true that this uncertainty is already present in for example a photon in high quality optical cavity.
If I make one mirror transparent, the photon starts leaking out => it's spectrum broadens.
So, I assume the energy uncertainty seeps in my system simply by...
A detuned cavity has indeed the same sort of energy problem that I don't get. I regret not putting it literally in my first post, it's too late to edit now.
The dynamics of an atom in a detuned cavity happens exactly how you describe, it oscillates, but the atom (or cavity depending on your...
I probably have a wrong way of looking at this, but I'm thinking of a wave packet in terms of a superposition of photons of different wavelengths and phase. So a superposition of a continuous range of states with different energy.
And it is in the collapse that I don't understand what the energy...
So, this is something I've never understood in detail.
If an excited system decays and emits a photon, the lifetime of the decay will broaden the spectrum of the photon right?
Basically just a Fourier transform of the "shape" of the emission in time to get the frequency components of the...
