I suppose the answer is no, since there is no reason to believe that it does. Or is there any? Has this been tested experimentally? Or is there an obvious reason that it does or does not?
Aidyan said:Hmm... sorry my question was ill posed. I mean the transition probability which should not depend from the quantum phase (squared modulus of the amplitude).
The Unruh effect applies to accelerating frames and by the equivalence principle one could expect something similar for a system at rest in a gravitational field. This paper could be of interestAidyan said:What I mean are the transition probabilities in QM, i.e. the probability between the initial and final state of a quantum system (atomic or nuclear transitions, scattering, etc.).[]
Since this is classical QM, my doubt was that this does no longer hold in the presence of a curved spacetime background and needs extension (not just with SR, as in QFT of the SM, but with GR). If so, transition probabilities change in the presence of gravity, which means that the radiative transition spectrum of matter changes, for instance that of falling into a BH (it is not just redshift, it is about the structure of the spectrum). I suppose it is something already extensively analyzed (especially in quantum gravity theories) but could not find a reference to that. I ask because eventually that should not be too complicate to check experimentally. Or is there an obvious reason to dismiss this altogether?
Gravity affects quantum transition amplitudes by altering the spacetime curvature, which in turn affects the behavior of particles. This can cause changes in the probability of quantum transitions occurring.
Yes, gravity can change the path of quantum particles by curving the spacetime around them. This can cause the particles to follow a different trajectory than they would in a flat spacetime.
Yes, gravity is a factor in quantum mechanics. It is one of the four fundamental forces of nature and plays a role in determining the behavior of particles at a quantum level.
Yes, the strength of gravity can affect quantum transition amplitudes. The stronger the gravitational force, the greater the curvature of spacetime, which can impact the probability of quantum transitions occurring.
Yes, there have been experiments that have demonstrated the effect of gravity on quantum transition amplitudes. For example, the Pound-Rebka experiment showed that the frequency of emitted photons from an atom changes when moving from a higher gravitational potential to a lower one, indicating a change in quantum transition probabilities.
