Incompatible moments A spinning charge (left) acts like a loop of current to produce a magnetic dipole moment (blue arrow). Distorting the electron's charge distribution (middle) produces an electric ...
No new particles: artist’s impression of how virtual particles could give the electron an electric dipole moment. (Courtesy: Nicolle Fuller/NSF) It is well known that the electron has a magnetic ...
The study of electric dipole moments (EDMs) offers a unique window into the violation of time-reversal symmetry, an effect that, when coupled with charge-parity (CP) violation, presents fundamental ...
