Decoherence in the solvable dynamics of N strongly driven atoms coupled to a cavity mode / M. Bina, F. Casagrande, A. Lulli. - In: OPTICS AND SPECTROSCOPY. - ISSN 0030-400X. - 108:3(2010), pp. 356-361. [10.1134/S0030400X10030070]
Abstract:
We present the exact solution of the dynamics of N two-level atoms strongly driven by an external coherent field and equally coupled on resonance to a cavity mode, in the presence of both cavity dissipation and atomic decay. Analytical results are presented for system and subsystem dynamics, showing how environment induced decoherence leads the system from pure to mixed states. In the limit of negligible atomic decay, where the system is known to exhibit decoherence-free subspaces, we present a detailed discussion of the decoherence function that can be monitored by atomic population measurements.
