Flemish Strings of Magnetic Solitons and a Non-Thermal Fixed Point in a One-Dimensional Antiferromagnetic Spin-1 Bose Gas

We find that thermalization in a quenched one-dimensional antiferromagnetic spin-1 Bose gas proceeds via a non-thermal fixed point through annihilation of Flemish-string bound states of magnetic solitons. A possible experimental situation is discussed.
