The fundamental solution of this system’s Hamiltonian is the Mehler kernel. The Landau levels equal the eigenvalues of a 2D analog of this system’s Hamiltonian. The squeeze operator can be used to act on the coherent (15[1])states of this system. Eigenfunctions in this system can be constructed by applying operators denoted“a” and “a-dagger”, (15[1])known as (*) ladder operators. (10[1])The Dulong-Petit law’s high-temperature limit of “3 k-sub B”is reflected in a lattice of these systems that Albert Einstein used to model heat capacity. Collective excitations in a lattice of these systems are known as phonons. The (-5[1])energy levels of this non-classical system are quantized in multiples of “h-bar omega”. For 10 points, name this quantum analogue of systems that obey Hooke’s law. ■END■
