A homogeneous magnetic field and inhomogeneous electric field can be used to store this substance if it is charged.
A homogeneous magnetic field and inhomogeneous electric field can be used to store this substance if it is charged. Andrei Sakharov proposed B violation to explain why this substance was less prevalent. This material is represented by a bar, indicating that it has undergone charge conjugation. The Dirac equation predicts this substance as holes in a Dirac sea, and along with its counterpart, this substance is produced in beta decay. A remnant of pair production, this substance interacts with its more common counterpart through annihilation. For 10 points, name this material consisting of particles like the positron, the opposite of matter.
