    "abstract": "We study the Loschmidt echo for a system of electrons interacting through\nmean-field Coulomb forces. The electron gas is modeled by a self-consistent set\nof hydrodynamic equations. It is observed that the quantum fidelity drops\nabruptly after a time that is proportional to the logarithm of the perturbation\namplitude. The fidelity drop is related to the breakdown of the symmetry\nproperties of the wave function.",
