    "abstract": "In this paper we present a comprehensive analysis of the coherence phenomenon\nof two coupled dissipative oscillators. The action of a classical driving field\non one of the oscillators is also analyzed. Master equations are derived for\nboth regimes of weakly and strongly interacting oscillators from which\ninteresting results arise concerning the coherence properties of the joint and\nthe reduced system states. The strong coupling regime is required to achieve a\nlarge frequency shift of the oscillator normal modes, making it possible to\nexplore the whole profile of the spectral density of the reservoirs. We show\nhow the decoherence process may be controlled by shifting the normal mode\nfrequencies to regions of small spectral density of the reservoirs. Different\nspectral densities of the reservoirs are considered and their effects on the\ndecoherence process are analyzed. For oscillators with different damping rates,\nwe show that the worse-quality system is improved and vice-versa, a result\nwhich could be useful for quantum state protection. State recurrence and swap\ndynamics are analyzed as well as their roles in delaying the decoherence\nprocess.",
