| contents | In this letter we study soliton crystals in the $(2+1)$-dimensional analogue model of the $(3+1)$-dimensional Adkins--Nappi model of nuclear physics. The baby $ω$-Skyrme model studied here is an $O(3)$ nonlinear $σ$ model coupled to a massive vector meson, the $ω$-meson. Using recently developed methods in the $(3+1)$-dimensional $ω$-Skyrme model we are able to construct soliton crystals in this $(2+1)$-dimensional baby $ω$-Skyrme model. The resulting crystals form a hexagonal lattice structure and are qualitatively and quantitatively similar to crystals observed in the standard baby Skyrme model. |
