    • Q-balls and charged Q-balls in a two-scalar field theory with generalized Henon-Heiles potentialPeer reviewedOpen access

      We construct Q-ball solutions from a model consisting of one massive scalar field ξ and one massive complex scalar field ϕ interacting via the cubic couplings g1ξϕ ϕ þ g2ξ3, typical of Henon-Heiles-like potentials. Although being formally simple, these couplings allow for Q-balls. In one spatial dimension, analytical solutions exist, either with vanishing or nonvanishing ϕ. In three spatial ...

    • ZN-balls: Solitons from ZN-symmetric scalar field theoryPeer reviewedOpen access 

      28 novembre 2022, BUISSERET, Fabien; Brihaye, Yves, CeREF Technique
      Article scientifique
      We discuss the conditions under which static, finite-energy, configurations of a complex scalar field ϕ with constant phase and spherically-symmetric norm exist in a potential of the form V(ϕ*ϕ, ϕ^N, ϕ^*N) with N ∈ N and N ≥ 2, i.e., a potential with a ZN-symmetry. Such configurations are called ZN-balls. We build explicit solutions in (3 + 1)-dimensions from a model mimicking effective field ...
