dc.descriptionThe behaviour of the topological susceptibility χin QCD with two colours and 8 flavours of quarks is studied at nonzero temperature on the lattice across the finite density transition. It is shown that the signal of χdrops abruptly at a critical chemical potential μ_c, much as it happens at the finite temperature and zero density transition. The Polyakov loop and the chiral condensate undergo their transitions at the same critical value μ_c. At a value μ_s of the chemical potential, called saturation point, which in our case satisfies μ_s > μ_c, Pauli blocking supervenes and consequently the theory becomes quenched.
