Possibility of dynamical symmetry restoration in the Gaussian overlap approximation

We analyze the symmetry-conserving-variational-dynamics and the time-dependent-generator-coordinate methods showing their equivalence for a large class of problems. The application to actual calculations involving the restoration of the rotational symmetry in nuclear dynamics is examined together wi...
