Description
We study the existence of BPS vortices in a Chern-Simons-CP(2) model in the presence of magnetic impurities. The minimization of the energy via the Bogomol’nyi-Prasad-Sommerfield (BPS) formalism allows us to obtain the first-order differential equations (or BPS equations) and the corresponding Bogomol’nyi bound. The magnetic impurity chose for our study is a Gaussian-type, then the numerical solutions of the BPS equations through the finite-difference technique verifies the occurrence of nonmonotonic regular solutions. Such a nonmonotonicity produced by the magnetic impurity induces the flipping of the magnetic field, and consequently, it also affects the electric sector.
KEYWORDS: TOPOLOGICAL, BPS VORTICES, CHERN-SIMOS, CP(2) MODEL.
