چکیده

We study the existence of cylindrically symmetric electro-magnetostatic solitary waves for a system of a nonlinear Klein–Gordon equation coupled with Maxwell’s equations in presence of a positive mass and of a nonnegative nonlinear potential. Nonexistence results are provided as well.

Sufficient conditions for the existence of Q-balls in gauge theories

We formulate a set of simple sufficient conditions for the existence of Q-balls in gauge theories. CERN-TH/97-382 December, 1997 ∗ email address: [email protected] † email address: [email protected] email address: [email protected] Abelian Q-balls are non-topological solitons that accommodate some conserved global charge at a lesser energetic toll than a collection of free sca...

Baryonic Q-balls as Dark Matter

Supersymmetric extensions of the Standard Model predict the existence of Q-balls, some of which can be entirely stable. Affleck–Dine baryogenesis can result in a copious production of stable baryonic Q-balls, which can presently exist as a form of dark matter. 1 Q-balls from Supersymmetry In a class of theories with interacting scalar fields φ that carry some conserved global charge, the ground...

Introduction.– Many nonlinear classical field theories on flat spacetime backgrounds admit soliton solutions. These nonsingular solutions describe particle-like, localised configurations with finite energy. There has been some interest in recent years in the issue of globally regular spinning soliton solutions. However, to the best of our knowledge, to date no stationary and spinning solitons w...

Light-induced gauge fields for ultracold atoms.

Gauge fields are central in our modern understanding of physics at all scales. At the highest energy scales known, the microscopic universe is governed by particles interacting with each other through the exchange of gauge bosons. At the largest length scales, our Universe is ruled by gravity, whose gauge structure suggests the existence of a particle-the graviton-that mediates the gravitationa...

Brane potentials and moduli spaces

It is shown that the supergravity moduli spaces of D1-D5 and D2-D6 brane systems coincide with those of the Coulomb branches of the associated non-abelian gauge theories. We further discuss situations in which worldvolume brane actions include a potential term generated by probing certain supergravity backgrounds. We find that in many cases, the appearance of the potential is due to the applica...
