At variance with the autonomous case, the phenomenon is here characterized by the vanishing of a previously positive Lyapunov exponent in the spectrum, which takes place for a broad range of the coupling strength parameter. Such a state is studied also for the case of chaotic oscillators with ill-defined phases due to the absence of a unique center of rotation. Different phase synchronization indicators are used to circumvent this difficulty}, language = {en} } @article{TokudaKurthsAllariaetal.2004, author = {Tokuda, I. and Kurths, J{\"u}rgen and Allaria, Eugenio and Meucci, Riccardo and Boccaletti, Stefano and Arecchi, Fortunato Tito}, title = {Predicting phase synchronization in a spiking chaotic CO2 laser}, issn = {1063-651X}, year = {2004}, abstract = {An approach is presented for the reconstruction of phase synchronization phenomena in a chaotic CO2 laser from experimental data.
