A set of states for this system forms a prototypical overcomplete basis for which one can apply E. C. G. Sudarshan’s P representation. The Hardy–Hille formula generalizes the propagator of this system, called the Mehler (10[1])kernel. (10[3]-5[1])Each index (-5[1])in a Fock (10[1])space is given by one of these systems, since a real scalar (-5[1])field (10[1])is represented by infinitely many of these systems coupled together. (10[1]-5[2])Roy (10[1])J. Glauber introduced this system’s canonical coherent states. An independent collection of these systems are modelled in an Einstein solid. (10[6]-5[2])Operators (10[1]-5[1])denoted a (10[1])and (-5[1])a-dagger (10[3]-5[1])are used to solve for this system’s (10[1])energy levels (10[1])and are denoted (10[1])“creation” and “annihilation,” (10[1])respectively. (-5[1])This system’s (10[1])energy levels are quantized in units of h-bar (-5[1])omega. (-5[1])For 10 points, name this non-classical analogue of a mass (10[1])on a spring. (10[3])■END■ (10[12]0[12])
