摘要: We predict the emergence of a time crystal generated by an incoherently driven and dissipative nonlinear optical oscillator, where nonlinearity also comes from dissipation. show that second-order phase transition light occurs in frame rotating at cavity frequency, while boundary (dissipative) emerges laboratory frame. relate these two phenomena using Liouvillian superoperator associated with Lindblad master equation its symmetries. These results connect thermodynamic limit, allowing to interpret them as same phenomenon terms spectrum, but just different frames.
