In this seminar I will consider the problem of avoided crossings in phononic crystals and explain a recent computationally strategy derived by Y. Lu and A. Srivastava to distinguish them from normal cross points. This process is essential for the correct sorting of the phononic bands and, subsequently, for the accurate determination of mode continuation, group velocities, and emergent properties which depend on them such as thermal conductivity and transport coefficients.
