Is simple diagonalization will lead to new particle?

25 April 2018 1 9K Report

If any Hamiltonian of any coupled system (e.g the photon-phonon coupled system in the simple optomechanical system) can be diagonalized then is it always true that the new form operator (combination of photon and phonon operator) will indicate the possibility of a new particle in nature.

Igor Goliney

Pretty much so. The particles you talk about are called polaritons. The only thing, "in nature" is too loud. In a sollid.
