Classical vs Quantum Mechanics: role of elementary excitations
arXiv:quant-ph/0308040 · doi:10.1016/j.physleta.2004.05.015
Abstract
Simple theorems relating a quantum mechanical system to the corresponding classical one at equilibrium and connecting the quantum eigenvalues to the frequencies of normal modes oscillations are presented. Corresponding to each quantum eigenfunction, a ` classical eigenfunction' is associated. Those belonging to `elementary excitations' play an important role.
