From Q-Walls to Q-Balls
We study Q-ball type solitons in arbitrary spatial dimensions in the setting recently described by Kusenko, where the scalar field potential has a flat direction which rises much slower than φ. We find that the general formula for energy as a function of the charge is, Ed ∼ Q d in spatial dimension d. We show that the Hamiltonian governing the stability analysis of certain Q-wall configurations...
متن کاملVortices, Q-balls and Domain Walls on Dielectric M2-branes
We study BPS solitons in N = 6 U(N)×U(N) Chern-Simons-matter theory deformed by an F-term mass. The F-term mass generically breaks N = 6 supersymmetry down to N = 2. At vacua, M2-branes are polarized into a fuzzy S3 forming a spherical M5-brane with topology R1,2×S3. The polarization is interpreted as Myers’ dielectric effect caused by an anti-self-dual 4-form flux T4 in the eleven-dimensional ...
متن کاملCharge-swapping Q balls.
Q balls are nontopological solitonic solutions to a wide class of field theories that possess global symmetries. Here we show that in these same theories there also exists a tower of novel composite Q-ball solutions where, within one composite Q ball, positive and negative charges coexist and swap at a frequency lower than the natural frequency of an individual Q ball. These charge-swapping Q b...
متن کاملSmall Q balls
We develop an adequate description of non-topological solitons with a small charge, for which the thin-wall approximation is not valid. There is no classical lower limit on the charge of a stable Q-ball. We examine the parameters of these small-charge solitons and discuss the limits of applicability of the semilcassical approximation. ∗ email address: [email protected] Non-topological solito...
متن کاملNoncommutative Q - balls
We obtain Q-ball solutions in noncommutative scalar field theory with a global U(1) invariance. The Q-ball solutions are shown to be classically and quantum mechanically stable. We also find that “excited Q-ball” states exist for some class of scalar potentials, which are classically stable in the large noncommutativity limit.
