• By adopting the background field method, the response of the dressed quark propagator to the presence of finite chemical potential is analyzed up to second order. From this we obtain a model-independent formula for the chemical potential dependence (up to second order) of the in-medium two-quark condensate and show by both Lorentz covariance arguments and explicit calculations that the O(μ) contribution to the in-medium two-quark condensate vanishes identically.
