Etymology
From Q (“charge”) + ball, coined by physicist Sidney Coleman. In physics, charge is often represented by the letter Q, and the soliton is spherically symmetric.
Meanings
-
A charged soliton that represents the lowest possible energy state of its components and is therefore stable.
Q-ball collisions are studied numerically on a two dimensional lattice for a range of Q-ball charges.
2001, Tuomas Multamäki, “Q-ball Collisions in the MSSM”, in Strong and Electroweak Matter 2000, page 348:If you're going to fly inside Mercury's orbit and hurl a bomb into the sun to burst its Q-ball (non-topological soliton) into pieces, I suggest that home may require a theoretical solution.
2008, Roger Ebert, Roger Ebert's Movie Yearbook 2009, page 880:A complex scalar theory in three dimensions with a cubic coupling can support classically stable, time-dependent, non-topological solutions to the equations of motion that carry a global charge Q, called Q-balls.
