Query: Nonthermal symmetry broken states in the strongly interacting Hubbard
  model   We study the time evolution of the antiferromagnetic order parameter after
interaction quenches in the Hubbard model. Using the nonequilibrium dynamical
mean field formalism, we show that the system, after a quench from intermediate
to strong interaction, is trapped in a nonthermal state which is reminiscent of
a photo-doped state and protected by the slow decay of doublons. If the
effective doping of this state is low enough, it exhibits robust
antiferromagnetic order, even if the system is highly excited and the thermal
state thus expected to be paramagnetic. We comment on the implication of our
findings for the stability of nonthermal superconducting states.
