There is a theoretical possibility of beyond-quantum nonlocality in the framework of general probabilistic theories. The authors give a protocol to detect beyond-quantum nonlocality with standard quantum devices.
Dissipative Dicke time crystals: An atom's point of view

The authors develop a non-equilibrium quantum theory for atoms with time-periodic cavity-mediated interactions and dissipation by eliminating the photonic modes. Their theory describes accurately the relaxation into stable time-crystalline steady states and is used to predict the phase transition lines.
