Figure 1: Illustration that an electron with an EDM violates time-reversal symmetry. Figure 2: Schematic of the physics underlying the experiment to search for the electron EDM. No known materials ...

Linear molecules can capture and bind free electrons through the permanent dipole moment interaction. Physicists have achieved laboratory confirmation of the existence of dipole-bound states.

The reason is that many physicists believe that electrons have a permanent electric dipole moment. An electric dipole moment is usually created when positive and negative charges are spatially ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. Most of the coverage of this adopts the framing of talking about ...

The result came from a search for the so-called electric dipole moment in the electron. A familiar example of a dipole is a bar magnet, which is shaped like a dumbbell with a north and a south pole.

Measuring zero: scientists have lowered the previous upper limit of the neutron’s electric dipole moment by 40%. (Courtesy: IOP Publishing) For more than 60 years, physicists have been searching for a ...

Such molecules have a permanent dipole moment which strengthens the interaction at a relatively great distance from the neutral nucleus and boosts the capture rate of free electrons. Observing ...
