Abstract: We demonstrate analytically that complex Langevin dynamics can solve the
sign problem in one-dimensional QCD in the thermodynamic limit. In particular, it is
shown that the contributions from the complex and highly oscillating spectral density of
the Dirac operator to the chiral condensate are taken into account correctly. We find
