I am trying to understand coherent states. As far as I could find there are three equivalent definitions and in general many sources start from a different one, still I fail to see their equivalence. ...
I'm researching a review article I'm writing on atomic clocks. In miniaturized versions of the technology they are using coherent population trapping to excite resonance in atoms. I don't really ...
Do small-angle coherent scattering experiments really see coherent effects over arbitrarily large distances?
Short version After integrating over all possible outgoing angles, the total cross-section of coherent elastic scattering from a fixed target of characteristic length $L$ scales like $L^4$. Does ...
Why incoherent source of waves have to be passed though a single slit for double slit interference pattern to occur?
Thomas Young used a single slit between the light source and the double slits. I can't understand why did he used the single slit, since the light from only one source is coherent already or isn't it? ...
If two waves are coherent, is it the same as them being in phase? Please correct if I'm wrong.
