Abstract
The study of two coupled systems having discrete eigenvalues leads naturally to the existence of doorway states, whether the coupled systems have a classical or quantal nature. Doorway states in classical phenomena are here exemplified by a membrane coupled to an acoustic cavity. These ideas are useful also to understand seismic data collected in Mexico City for recent earthquakes, which are naturally interpreted along the lines of the acoustic model presented here.
