@article { , title = {Generalized Dicke nonequilibrium dynamics in trapped ions}, abstract = {We explore trapped ions as a setting to investigate nonequilibrium phases in a generalized Dicke model of dissipative spins coupled to phonon modes. We find a rich dynamical phase diagram including superradiantlike regimes, dynamical phase coexistence, and phonon-lasing behavior. A particular advantage of trapped ions is that these phases and transitions among them can be probed in situ through fluorescence. We demonstrate that the main physical insights are captured by a minimal model and consider an experimental realization with Ca+ ions trapped in a linear Paul trap with a dressing scheme to create effective two-level systems with a tunable dissipation rate.}, eissn = {0031-9007}, issn = {0031-9007}, issue = {2}, journal = {Physical Review Letters}, publicationstatus = {Published}, publisher = {American Physical Society}, url = {https://nottingham-repository.worktribe.com/output/721519}, volume = {112}, year = {2014}, author = {Genway, Sam and Li, Weibin and Ates, Cenap and Lanyon, Benjamin P. and Lesanovsky, Igor} }
