A pair of coupled quantum dissipative oscillators, serving as a model for ananosystem, is here described by the Lindblad equation. Its dynamic evolutionis shown to exhibit the features of decoherence (spatial extent of quantumbehavior), correlation (spatial scale over which the system localizes to itsphysical dimensions), and entanglement (a special quantum feature making itsappearance first in such bipartite systems) as a function of the couplingconstants of the Lindblad equation. One interesting feature emerging out ofthis calculation is that the entanglement may exhibit revivals in time. Aninitially entangled state need not remain so for all time and may exhibitregions of nonentanglement. Interpreting the parameters of the Lindblad theoryas environmental features in certain experimental situations, this modelcalculation gives us clues to possible control of decoherence, correlation, andentanglement. We indicate possible interpretation of the Lindblad parameters ascontrol parameters in more general contexts of some recent experiments.Comment: 24 pages, 4 figure
