Query: Quantum discord dynamics in structured reservoirs   The non-Markovian master equations are derived to study quantum discord
dynamics of two qubits coupled to a common reservoir and two independent
reservoirs, respectively. We compare the dynamics under different parameters,
such as reservoir spectra and resonant parameters, at high temperature and at
zero temperature. The results indicate that the dynamics at these two extreme
temperatures share similar characters, as well as differences.
