      abstract     = {We consider space-time correlations in driven diffusive
                      systems which undergo a fluctuation into a regime with an
                      atypically large current or dynamical activity. For a single
                      conserved mass we show that the spatiotemporal density
                      correlations in one space dimension are fully determined by
                      conformal field theory with central charge c=1,
                      corresponding to a ballistic universality class with
                      dynamical exponent z=1. The full phase diagram for general
                      atypical behavior exhibits the conformally invariant regime
                      and, for atypically low current or activity, a region of
                      phase separation. The phase transition line between these
                      two regimes corresponds to typical behavior and the dynamics
                      belongs to the Kardar-Parisi-Zhang universality class with
                      dynamical exponent z=3/2, except for a diffusive point with
                      z=2. The exact universal dynamical structure function is
                      obtained in explicit form from the one-dimensional
                      asymmetric simple exclusion process with periodic and open
                      boundaries in the limit of maximal current.},
