Query: Conditions for the freezing phenomena of geometric measure of quantum
  discord for arbitrary two-qubit X states under non-dissipative dephasing
  noises   We study the dynamics of geometric measure of quantum discord (GMQD) under
the influences of two local phase damping noises. Consider the two qubits
initially in arbitrary X-states, we find the necessary and sufficient
conditions for which GMQD is unaffected for a finite period. It is further
shown that such results also hold for the non-Markovian dephasing process.
