Emergent AC Effect in Coupled Nonreciprocal Condensates

This paper explores a novel phenomenon in coupled condensates, where an AC Josephson-like effect emerges without an external bias. The research is significant because it reveals new dynamical phases driven by nonreciprocity and nonlinearity, going beyond existing frameworks like Kuramoto. The discovery of a bias-free, autonomous oscillatory current is particularly noteworthy, potentially opening new avenues for applications in condensate platforms.
