Abstract: We compute the effective action for covariantly constant gauge fields that are solutions of the sourceless Yang–Mills equation and have the form of magnetic flux tubes. They represent a superposition of infinite many alternating monopole/anti-monopole pairs situated at infinity, with each pair having a structure similar to the Nielsen–Olesen magnetic flux tube. The chromomagnetic flux tubes condensation is stable and indicates that the Yang–Mills vacuum state is highly degenerate.
