Hello! I have a 3 level system with energies ##E_0##, ##E_1## and ##E_2## and 2 time varying electric fields, the first one connects ##E_0## and ##E_1## while the second one connects ##E_0## and ##E_2## with Rabi frequencies ##\Omega_1## and ##\Omega_2## and the frequencies of the electric...
I am thinking about a situation in general relativity which may be in textbooks but I have not been able to find it. I appreciate that there is the geodesic deviation equation for the world line of an observer and a nearby free-falling particle, but I think I need something different.
So we...
