In this talk, I will give an overview over the emerging topic of latent symmetries. Although they are in general not apparent from a geometric inspection of the system, they still have a powerful impact. This includes the induction of local symmetries on the system’s eigenstates or even degeneracies in the eigen-value spectrum. Their study thus allows to gain knowledge about the system’s structure that remains hidden from a direct observation. The concept is exemplified through several wave-physical examples.
