In an electric field, most of the electrons are oriented so that their dipole moment is parallel to the field. Fewer are oriented in the other direction. This should lead to a measurable ...

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 strength of this electric dipole interaction is measured ... of charge would have zero dipole moment-- no matter what direction you apply the field in, you get the same total energy.

For the moment this dipole remains hypothetical ... rely on the fact that an EDM would cause a neutron’s spin axis to rotate when exposed to an electric field. To pick out this rotation they first ...

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.

What's more, these insulators generate electric quadrupole or octupole ... made it possible to define the dipole moment of a crystal through a particular application of the Berry phase—a ...

However, we can also find an approximate value for the magnitude of the electric field due to a dipole as long as we are looking at the field along the axis of the dipole or perpendicular to the axis.
