Exceptional points are a distinct type of spectral singularity in non-Hermitian systems and their intriguing physics are in study with optical exceptional points. Exceptional points are singularities in the energy functions of a physical system, where two light modes can coalesce to produce unusual effects. Mechanical oscillators are a system beyond photonics that can couple with many physical systems to further explore within mechanical sensing, topology energy transfer and non-reciprocal dynamics.
