Instead of a commutation relation [â, â¹] = 1 which is true for photons, assume that the creation and annihilation operators satisfy âât +â¹â = 1 Show that the number operator N = â¹â satisfies âÑ = (1 – Ñ)â â¹Ñ = (1 - №)ât Prove that if one eigenvalue of N is n = 0, there is only one other eigenvalue, n = 1. (This means that there cannot be more than one particle in the particular state associated with the operators ¡ât and â.)
