Abstract: We study the two-dimensional C P n−1 non-linear σ -models at a finite temperature, T , within the 1/ n expansion. We show that permanent confinement of their fundamental particles is a strictly zero-temperature phenomenon. The quantum statistical fluctuations suppress the non-trivial topological structure of the classical C P n−1 models and consequently the background topological density vanishes at T ≠ 0 for an infinite space “volume”. These models do not depend on the vacuum angle θ at any T ≠ 0.
