Abstract
Based on the phenomenological Ginzburg-Landau approach, we investigate phase solitonic states in a class of three-component superconductors for mesoscopic doubly-connected geometry (thin-walled cylinder) in external magnetic fields. Analysis of the Gibbs free energy of the system shows that solitonic states in a three-component superconductor are thermodynamically metastable and separated from the ground state by a sizable energy. Our results demonstrate that despite of the presence of the zoo of phase solitons states earlier proposed method [Phys. Rev. B 96, 144513 (2017)] for the detection of BTRS in multiband superconductors remains valid and useful.
