Range of forces from mass of force carrier?
Why is $\frac{\hbar}{mc}$ a good estimate of the range of the four forces, where $m$ is the mass of the carrier particle of the force? Inputting the pion mass gives $1.4\ \mathrm{fm}$ for the hadronic ...

Rotating Frame with degenerate levels
I'm working with a angular momentum transition J=0 -> J=1 with no applied magnetic field; so, the upper level has degeneracy 3. This atom is coupled with an electric field propagatin in the ...
