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 ...

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 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.

The strength of this electric dipole interaction is measured by a thing called an "electric dipole moment," and in classical electromagnetism, you calculate these all the time for macroscopic ...

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 ...

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 ...

One example is an exotic property of electrons called the electric dipole moment, a small difference between the center of mass of an electron and its center of charge. Such a displacement has ...

No, they don't. We can call the product of q and s the electric dipole moment. It would actually be a vector, but just don't worry about that for now. Using the same idea for a bar magnet ...

A ferroelectric material is one whose equilbrium state has a bulk electric dipole moment. This occurs in solid ceramics when ground state crystal structure involves spatial separation of ionic charges ...
