The simple problem solved by Eugene Wigner and John von Neumann about a century ago in quantum mechanics, could stimulate research on a whole spectrum of resonant phenomena in wave physics 15 years ago. We will talk about bound states in the continuum.
Due to their huge radiative lifetime, bound states in the continuum have found many applications in various fields of physics devoted to wave processes.
In optics and photonics in particular, these states offer huge opportunities to create compact high-Q resonators and metasurfaces required for biosensing and enhancement of nonlinear optical effects and light-matter interaction.
There will be the history of the field, the basic physical mechanisms in the formation of bound states in the continuum, and specific examples of structures supporting such states: metasurfaces, chains and resonators.
