Query: Quantum discord and measurement-induced disturbance in the background of
  dilaton black holes   We study the dynamics of classical correlation, quantum discord and
measurement-induced disturbance of Dirac fields in the background of a dilaton
black hole. We present an alternative physical interpretation of single mode
approximation for Dirac fields in black hole spacetimes. We show that the
classical and quantum correlations are degraded as the increase of black hole's
dilaton. We find that, comparing to the inertial systems, the quantum
correlation measured by the one-side measuring discord is always not symmetric
with respect to the measured subsystems, while the measurement-induced
disturbance is symmetric. The symmetry of classical correlation and quantum
discord is influenced by gravitation produced by the dilaton of the black hole.
