When studying the properties of systems in nature and technology, we often look at their eigenvalues and eigenfunctions because they tell us something about how the system evolves and how it responds to external perturbations. For many technical applications, such an analysis is important to guarantee safety and operability. When dealing with complex systems, however, this is often a challenging task. A prominent example are thermoacoustic oscillations, an undesirable phenomenon that occurs in many combustion devices. I will discuss in this talk how these instabilities manifest in gas turbine engines, and how we can use tools that originated from the field of quantum mechanics to aid the spectral analysis of such systems. The analogies we draw upon largely revolve around spatial symmetries, which can be found in many configurations of technical relevance.
